Seeing as how no teams have played a down yet, it makes it difficult to gauge which defenses will be improved in 2012. But based on the decisions they made in free agency and the draft, these five teams should be improved defensively next season.

Buffalo Bills
Think of the impact that Julius Peppers has had with the Bears the past two seasons – that’s exactly what Mario Williams could do for the Bills in 2012. Buffalo’s defense struggled last season mostly because the pass rush was non-existent. So GM Buddy Nix lured Williams to Buffalo this offseason and made sure he didn’t leave the city without first signing a contract. Nix also signed Mark Anderson, an experienced situational pass rusher that should benefit from playing opposite Williams in the Bills’ “new” 4-3. Adding cornerback Stephon Gillmore should also help Buffalo on the backend while Nigel Bradham and Tank Carder will add depth to the linebacker corps. We’ll have to see how the Dave Wannstedt hire pans out but for now, there’s no question the Bills have upgraded their pass rush in one offseason.

Dallas Cowboys
With the moves they made this offseason, the Cowboys’ defense could transform from a top 15 unit into a top 10. DeMarcus Ware, Jay Ratliff, Anthony Spencer and Sean Lee comprise a solid front seven but Dallas struggled on the back end in 2012. So Jerry Jones invested $50.1 million and a second round pick on his cornerback positions this offseason with the additions of free agent Brandon Carr (the best CB on the market) and first-round pick Morris Claiborne (the best CB in the draft). It’s never guaranteed that a big money free agent or a rookie will make an immediate impact but at least on paper, the Cowboys have definitely improved their secondary. The signing of Dan Connor was also somewhat underrated as well. He struggles at times in coverage and he’s not a pass rusher but he’ll be perfect for what Dallas signed him for: an insider ‘backer that can bolster the run defense.

Atlanta Falcons
The Falcons were productive this offseason in re-signing John Abraham (their best and sometimes only pass rusher last season), safety Thomas DeCoud (who is better than his reputation would suggest), and situational pass rusher Kroy Biermann (who appeared to be distracted last year, although marrying a reality TV star and parenting a newborn will do that to a man). But fans grew aggravated by GM Thomas Dimitroff’s inactivity in free agency and expressed disappointment that the team didn’t go after big money talent like Mario Williams. (Fans were also upset that the team didn’t re-sign MLB Curtis Lofton, who wound up landing with division rival New Orleans.) But the day before the draft Atlanta swung a deal that could only be considered as a steal. Acquiring a three-time Pro Bowler in Asante Samuel for a seventh round pick was a bargain for any team, especially one that struggled getting off the field last season on third downs. Furthermore, the hiring of defensive coordinator Mike Nolan was a huge coup for the Falcons, who should be more aggressive and better equipped to handle explosive offenses like New Orleans, Green Bay and New York. No, the Falcons weren’t very active in free agency this year. But the re-signing of Abraham, the acquisition of Samuel and the hiring of Nolan should be more than enough to make this an improved Falcons squad.

Philadelphia Eagles
After struggling early in the season, the Eagles wound up being a top 10 defensive unit in 2011. But here’s why they’ll be improved in 2012. Juan Castillo has a full year of experience under his belt and the pressure he faced last year being a first-time defensive coordinator should lessen. Andy Reid also hit a home run in this year’s draft. Fletcher Cox has top 10 talent and the Eagles landed him at No. 12 (after moving up). Mychal Kendricks is undersized for the position but he was extremely productive at Cal, he hits like a Mac truck and he plays at 110mph every down. Vinny Curry is raw but he has potential as a pass rush and the only reason Georgia cornerback Brandon Boykin fell to the fourth round was because he broke his leg at the Senior Bowl and was limited in pre-draft workouts. Otherwise, he’s a second-round prospect. Re-signing Derek Landri was also good for depth purposes and acquiring DeMeco Ryans from Houston should help the run defense.

St. Louis Rams
The Rams are a bit of a wildcard but considering they ranked 22nd in yards allowed, 31st in run defense and 26th in points allowed, there’s really nowhere to go but up. There are five moves the Rams made this offseason that should prove to beneficial in 2012. The first was hiring defensive-minded Jeff Fisher as head coach, who brought assistants like Mike Waufle and Chuck Cecil with him to St. Louis. The Rams also added scrappy cornerback Cortland Finnegan and defensive tackle Kendall Langford, who is a freaking house. Drafting run-stuffing DT Michael Brockers to play alongside Langford was also big and former Florida cornerback Janoris Jenkins could prove to be worth the gamble that new GM Les Snead took in the second round. Keep an eye on William Hayes, too. He was limited last year because of a shoulder injury he suffered in Week 1 but he’s someone that could potentially see his playing time increase because he’s he can play the run and provide some pressure. The Rams screwed the pooch by not taking an outside linebacker in the second round, but all in all they had a productive offseason and should be improved next year.

In three games this season against Baltimore pitchers, Albert Pujols had zero hits, zero home runs, zero RBI and just one run scored.

In one game versus Baltimore pitchers, Josh Hamilton had five hits, four home runs, eight RBI and four runs scored.

Yiiiikes.

With his historic performance on Tuesday night, Hamilton became the first American League player to go 5-for-5 with four home runs in one game. He also set an AL record with 18 total bases and became the 16th player to hit four dingers in a single game. Carlos Delgado was the last player to achieve the feat back in 2003 as a member of the Toronto Blue Jays.

It’s rather amazing to think that Hamilton, one of the best sluggers in the game, doesn’t even have a contract past this season. From the Rangers’ perspective, it’s understandable that they don’t want to pony up $100-plus million for a player that has battled off-field demons his entire career but come on – he’s now hitting over .400 and he has 14 long balls on the year. That’s absolutely incredible, I don’t care how early in the season it is.

There’s an argument to be made for St. Louis but thanks in large part to Hamilton, Texas still has the best offense in the league. It wouldn’t be surprising to see the Rangers make another deep postseason run, although let’s not get ahead of ourselves. There’s still a lot of baseball left to be played.

It’s almost comical the way Hamilton and the Dodgers’ Matt Kemp are destroying opposing pitcher this year. Kemp almost looks like he’s not even trying and that’s meant to be a compliment. As of this writing, Hamilton now has more home runs than the entire San Diego Padres team.

For those scoring at home, Hamilton is now on pace to hit 75 home runs this season.

Mike Shanahan apparently only needed one rookie minicamp to name Robert Griffin III his starting quarterback.

My question is, what took him so long? I’m shocked Shanahan didn’t walk to the podium at Radio City Music Hall and made the announcement while Griffin was busy hugging Roger Goodell.

If anyone is surprised that Shanahan has already made this decision, don’t be. He gave up first-round picks in 2012, 2013 and 2014, as well as the team’s second-round pick this year so why not start Griffin right away? There’s no reason to wait.

“Any time you pick a player with the second pick of the draft and you give up another two No. 1’s and No. 2 and you move up four spots, you’ve got a game plan in mind,” Shanahan told Mike Jones of the Washington Post. “We’re going to adjust our system to what he feels comfortable with, and we’ll watch him grow, and we’ll do what we feel like he does the best.”

You never want to rush a quarterback when he’s not ready but what is Shanahan to do, hold an open competition at quarterback when everyone knows Griffin is his guy? Shanahan has seen enough out of Rex Grossman to know that he can’t win with him under center for 16 games. Why delay getting Griffin much needed experience in his first season?

Given the success that Matt Ryan, Sam Bradford, Cam Newton and Joe Flacco had as rookies over the past four seasons, there’s no reason to think that Griffin can’t turn the Redskins into an immediate winner. But his success will depend on how well Washington’s shaky offensive line protects him next season.

Left tackle Trent Williams tested positive for banned substances ten times in September and October according to a report by Pro Football Talk.com last December. Thus, he’s one more screw up away from potentially serving a long-term suspension.

On the other side, Jammal Brown continues to battle lingering left hip and groin issues while left guard Kory Lichtensteiger is coming off November ACL surgery. Granted, the Redskins did draft three offensive linemen last month but who knows whether or not any of those players will be able to make an impact from Day 1.

But even if the Redskins decided to use a banner made of papier-mâché as their offensive line, Griffin will be their starter. He was destined for that role the second Shanahan swung that trade with the Rams.

In an op-ed for Sunday’s edition of the Chicago Sun-Times, Bears receiver Brandon Marshall discussed Junior Seau’s passing and the difficulty that NFL players have with depression.

“Looking at the situation with Seau and other cases with retired athletes, I think our focus should be more on why the transition seems to be so hard after football. As athletes, we go through life getting praised and worshipped and making a lot of money. Our worlds and everything in them — spouses, kids, family, religion and friends — revolve around us. We create a world where our sport is our life and makes us who we are. When the game is taken away from us or when we stop playing, the shock of not hearing the praise or receiving the big bucks often turns out to be devastating. The blueprint I am creating for myself will help not only other athletes, it will help suffering people all over.”

Marshall makes an excellent point. What happens when fans stop cheering their name? What happens when they’re not adored and admired? What happens when they stop getting everything handed to them in life?

That last question isn’t meant to be crass – it’s reality. Because of their gifted athletic abilities, players are privileged from a very young age. They’re used to people making them feel special and handing them opportunities. All of a sudden when that’s gone, what happens? Talk about a transition.

Marshall’s right – what happens when the lights finally go down? Many athletes only know one life and once that’s over, they often don’t know what to do. I talk to former athletes and a lot of them same thing: It’s jarring when their playing careers are over. Some know how to handle it, others don’t.

We can assume that Seau had mental troubles stemming from using his head as a battering ram for 20 seasons in the NFL. And if he had the same condition as Dave Duerson, then we’ll find out soon enough.

But maybe Marshall is right and concussions aren’t the only problem – they’re just part of a bigger, more frightening picture.

The 138th running of the Kentucky Derby takes place today, Saturday, May 5. If you’re looking for some guaranteed winners to pay off the mortgage and set up the kids’ college funds, they’re below.

WIN: Dullahan (8/1)
Apparently Dullahan likes the synthetic surfaces better than dirt but I like the trends attached to this contender. Three-time Derby winner Kent Desormeaux will have the mount today and the No. 5 post position has produced 12 Kentucky Derby winners since 1900, which is tied with the rail for most victories. Dullahan is also coming off a victory at the Grade I Toyota Blue Grass and finished second at the Grade III Palm Beach on March 11. The fact that he doesn’t have six career races under his belt scares me a little, but Dullahan has displayed great closing speed in recent races and I like him to at least finish in the money.

PLACE: Bodemeister (13/10)
Bodemeister is the favorite to win Saturday’s race, although Union Rags has the exact same odds. Either way, what attracts me most to Bodemeister is the winning combination of trainer Bob Baffert and jockey Mike Smith. Baffert has won three Kentucky Derby races in his career (2002, 1998, 1997), while Smith won the 2005 Derby aboard Giacomo. Bodemeister only has four career races under his belt but he finished second at the Grade II San Felipe on March 10 and won the Grade I Arkansas Derby on April 14. No horse has won the Derby that has not run as a 2-year-old since 1888 but I like Bodemeister to finish in the money.

SHOW: Take Charge Indy (11/1)
Considering he’s 5-0 in his career, I thought long about putting Gemologist in the money. But at the end of the day, how can you go against Calvin Borel? The man has won three of the last five Kentucky Derby races and he’ll be coming out of the No. 3 post position, which means he’ll be able to get to the rail faster. Take Charge Indy is also coming off a victory at the Grade I Florida Derby in which he went wire-to-wire.

Other contenders that caught my eye: Gemologist (8/1) and Went The Day Well (25/1)
As previously mentioned, Gemologist hasn’t lost in his five-race career, while Went The Day Well is trained by H. G. Motion and ridden by John Velazquez, who were the winning pair for Animal Kingdom last year.

One of the better storylines from the first month of the 2012 MLB season was the Washington Nationals, who now have a walking headline playing right field for them.

Nationals general manager Mike Rizzo admitted to the media that rookie phenom Bryce Harper is unlikely to be sent back down to the minors after the club called him up a week ago.

“We’re no dumb either,” Rizzo told the Washington Post. “This guy is performing admirably in the big leagues. We feel he’s got a chance to really impact the ball club. He’s a special talent. So you have to throw ordinary development curves out the window if you have to.”

Harper is currently batting .375 over his first 16 at bats and he’s shown off his rocket of an arm. He’s also playing extremely hard, most notably running out routine fly balls on the base paths. Say what you want about Harper being overly confident (also known as “cocky”), but the guy is “Charlie Hustle” out there right now.

The bottom line is that Bryce Harper is good for baseball. All good, young players are. And if he succeeds, he’s going to be great for the game for a very long time. Hopefully he’ll continue to rake, play good defense and flash speed on the base paths.

This game needs its budding young stars and it’s great that, at least for the moment, Harper is here to stay.

Perhaps the Ravens didn’t select Alabama defender Courtney Upshaw just because he was a value in the second round.

As it turns out, they’re going to need him to be a major contributor this season.

According to 105.7 The Fan in Baltimore, Terrell Suggs is out of the 2012 season with a torn Achilles’ tendon. ESPN’s Adam Schefter has already confirmed the news (so you know it’s true) and reported that Suggs injured himself playing basketball. The reigning Defensive Player of the Year will apparently have surgery sometime next week.

This is a massive blow for a team that has had Super Bowl aspirations the last couple of seasons. Suggs is coming off his best season as a pro while recording career highs in both sacks (14) and forced fumbles (7). He was part of a Baltimore defense that finished third in both yards (4,622) and points allowed (16.6).

Heading into the draft it didn’t appear as though linebacker was that big of a need for the Ravens, even after Jarrett Johnson signed a four-year deal with the Chargers in free agency. But with Suggs on the shelf, the Ravens were fortunate that a first-round talent like Upshaw fell to them in the second round. (Although GM Ozzie Newsome clearly wasn’t desperate to add marquee defensive help since he traded out of the first round entirely. Still, he was fortunate that Upshaw slid out of the first round.)

The Ravens will now rely on Upshaw, Paul Kruger and Pernell McPhee to pressure the quarterback next season. 2011 second round pick Sergio Kindle was reportedly on the roster bubble (or would be heading into training camp), but his job appears to be safe for now. The Ravens are going to need bodies after the injury to Suggs.

The North County Times reported on Wednesday that former Chargers, Dolphins and Patriots linebacker Junior Seau passed away after a self-inflicted gunshot to the chest. Seau was 43 years old.

There have been conflicting reports about who found Seau’s body at his Oceanside, California home. Some media outlets have stated that it was his housekeeper that discovered his body, while others have reported that it was Seau’s girlfriend who eventually found him and called authorities. A handgun was found nearby and police have confirmed that Seau committed suicide.

Seau was drafted fifth overall in 1990 by the San Diego Chargers, whom he played with for 12 years before he was traded to the Miami Dolphins in April of 2003. He later signed with the New England Patriots for three years before leaving the game following the 2009 season.

During his 20 years in the NFL, Seau racked up 1,849 tackles, 56.5 sacks and 18 interceptions. He went to 12 Pro Bowls during his career and was named All-Pro 10 times. He was a part of two AFC Championship teams (1994 Chargers and 2007 Patriots) and was named AFC Player of the Year in 1994. He’s a member of the San Diego Chargers Hall of Fame and was named NEA NFL Defensive Player of the Year in 1992.

Just over one year ago, former Chicago Bears safety Dave Duerson committed suicide in the same fashion as Seau. Three months later researcher neurologists at Boston University confirmed that Duerson suffered from a neurodegenerative disease linked to concussions.

Renowned for his hard hits and raw energy, Seau was easily one of the best outside linebackers to have ever played the game.

With April now in the books, what were some of the biggest surprises through the first month of the 2012 MLB Season? I’ve outlined five shockers below.

Pujols suddenly can’t hit.
It’s not completely surprising that Albert Pujols is slumping at the plate to start the season. After all, midway through April last year he was hitting just .222 for the Cardinals with only one home run. But who could have predicted that Pujols would look this bad in his first full month with the Angels? He has zero home runs, is hitting just .217 and has collected only four RBI. He’s clearly pressing right now and it doesn’t look like he has a clue on how to shake out of his funk. He’ll eventually come around but thus far, his struggles at the dish have been national news.

The Cardinals’ pitching staff.
Who would have thought that Adam Wainwright would be the biggest issue facing the Cardinals’ pitching staff through the month of April? Entering Tuesday’s action, Wainwright was sporting a 0-3 record with a 7.32 ERA. Meanwhile, Kyle Lohse and Lance Lynn are both 4-0 and Jake Westbrook is 3-1 with a 1.30 ERA. In fact, Wainwright is the only Cardinals’ starter that has an ERA over 2.78. When Wainwright eventually figures it out (and he will), and Lohse, Lynn, Westbrook and Jaime Garcia continue to pitch as well as they have, the Cardinals will be extremely tough to beat in the National League again this year.

The Washington Nationals are in first place.
Ask the Pirates – being in first place after the first month of the season or even at the All-Star Break (as Pittsburgh was last year) doesn’t mean squat. But the Nationals have been fun to watch regardless. Adam LaRoche has been fantastic, as he’s leading Washington in average (.329), home runs (4), RBI (17), OBP (.415) and total hits (27). But the other story has been the Nationals’ pitching, as four of their five starters have ERAs south of 2.00. The organization just brought up rookie phenom Bryce Harper too, which virtually guarantees that the Nationals will be relevant for a little while longer.

The Tigers aren’t in first place in the AL Central.
Blame the media for this one. Once the Tigers signed Prince Fielder last offseason, everyone just assumed that the rest of the AL Central would just roll over and play dead. But while the Tigers have had issues with their starting pitching, the Indians (11-9, first place) and White Sox (11-11, tied for second) have played well. Justin Verlander continues to be the rock of the rotation and Drew Smyly has been a pleasant surprise, but Rick Porcello and Max Scherzer have been disastrous. Porcello is currently sporting an ERA of 6.45 while Scherzer’s ERA is an abysmal 7.77. It doesn’t matter if Fielder and Miguel Carbera continue to hit the snot out of the ball – if the Tigers’ pitching doesn’t come around then there could be an upset brewing in the AL Central.

The Dodgers have the best record in the NL.
Ah, the power of Magic. Apparently all it took for the Dodgers to start playing well was for them to be sold. Los Angeles is currently sitting atop the NL West standings at 16-7, which includes a dazzling home record of 10-2. Matt Kemp has been ridiculous through 23 games, leading the league in batting average (.417), home runs (12) and RBI (25, tied with Texas’ Josh Hamilton). Better yet for L.A. Andre Ethier (.276, 5 HRS, 24 RBI) is actually contributing as well. If the pitching continues to be as good as it has (Clayton Kershaw is 2-0 with a 1.78 ERA while Chad Billingsley is 2-1 with a 2.64 ERA), then the Dodgers will prove that their hot start isn’t a fluke.
