Here are quick-hit previews for all of today’s action in the NFL.

Dolphins at Falcons, 1:00PM
The Falcons have issues in their secondary that Dolphins quarterback Chad Pennington can exploit. Atlanta had trouble getting off the field on third downs in preseason and the Dolphins excel at moving the ball methodically down the field. Conversely, Miami must keep up with Atlanta’s high-powered offense, which could be tough given how potent Matt Ryan and company looked in preseason.

Broncos at Bengals, 1:00PM
This game features the highly anticipated return of quarterback Carson Palmer, who will be without receiver T.J. Houshmandzadeh this year. It’ll be interesting to see if Chad Ochocinco can rebound from a poor ’08 campaign and re-establish a rhythm with Palmer. For Denver, new head coach Josh McDaniels gets to unveil his offense, which should include receiver Brandon Marshall, although his playing status is still somewhat up in the air. The player I’m keeping an eye on today is rookie running back Knowshon Moreno, who could excel in McDainels’ pass-happy offense as a receiver out of the backfield.

Vikings at Browns, 1:00PM
Even though this will be Brett Favre’s Vikings debut, Adrian Peterson will remain the focal point for Minnesota’s offense. Rookie Percy Harvin is expected to see a ton of playing time and could be used as Brad Childress’s X-factor. The Browns will find it tough to move the ball on the ground today, as Minnesota will have their Williams Wall intact. Quarterback Brady Quinn will be counted on to make plays in the passing game and it’ll be interesting to see if Braylon Edwards can put his tumultuous offseason behind him. One player to watch for the Browns is Joshua Cribbs, who is coming off a great preseason and could be used in a variety of ways today.

Jaguars at Colts, 1:00PM
Jacksonville is looking to bounce back from a disastrous ’08 season, one in which they were supposed to contend for the Super Bowl and instead found themselves at the bottom of the AFC South. Jack Del Rio’s Jags have always played the Colts tough and they could take advantage of Indy not having safety Bob Sanders in their secondary. The most intriguing matchup today will be Colts receiver Reggie Wayne against Jaguars corner Rashean Mathis. If the now-healthy Jags can keep Peyton Manning and company contained, Jacksonville could sneak away with a win.

Lions at Saints, 1:00PM
Rookie quarterback Matthew Stafford will make his pro debut today in New Orleans and it’ll be interesting to see how he fares against the Saints’ secondary, which features newbies Darren Sharper, Jabari Greer and rookie Malcolm Jenkins. In all actuality, Stafford probably won’t have much of an impact either way on the outcome of this game as Saints’ QB Drew Brees should tear apart a Lions’ defense that is severely devoid of talent.

Cowboys at Bucs, 1:00PM
Now that T.O. is in Buffalo, the spotlight is on quarterback Tony Romo to take Dallas to the next level. The Cowboys are loaded with talent, but haven’t been able to get over the hump the past couple years. They’ll have a good chance to start the season on the right foot today in Tampa, while the Bus try to get adjusted to a new head coach and a new defensive coordinator. Dallas should feast on inconsistent quarterback Byron Leftwich, who often holds onto the ball too long in the pocket and is prone to making mitakes. How will Tampa’s defense fare without coordinator Monte Kiffin?

Eagles at Panthers, 1:00PM
Philadelphia has Super Bowl on its minds after stocking their roster with new talent this offseason. Jason Peters, LeSean “Shady” McCoy and Jeremy Maclin will all make their Eagle debuts today against a Panthers team that will provide a tough test. It’ll be interesting to see how Philadelphia’s defense does against one of the league’s top running games without middle linebacker Stewart Bradley, who was lost for the season after suffering an injury in practice. Will DeAngelo Williams have a field day for the Panthers? Can quarterback Jake Delhomme bounce back from the horrendous outing he had in last year’s playoffs?

Chiefs at Ravens, 1:00PM
Baltimore will unveil its new-look defense (one that will feature more 4-3 fronts instead of their standard 3-4), while the Chiefs will display its new offense under head coach Todd Haley, who replaced Herm Edwards in he offseason. Tyler Thigpen will start under center today for KC as Matt Cassel, who suffered an injury in preseason and could miss the first couple games. Thigpen has starting experience, although Baltimore’s defense has a way of making any quarterback look bad.

Jets at Texans, 1:00PM
Rookie Mark Sanchez will make his pro debut today on the road against a Houston team that feels as though it’s ready to make a playoff run. In order for the Texans to have success this season, quarterback Matt Schuab must stay healthy. Look for Houston to get running back Steve Slaton involved in the passing game early and for the Texan defense to fluster Sanchez with a variety of blitzes. If New York can run the ball against a Houston team that struggled last year stopping opponents’ ground games, Sanchez and the Jets will be fine.

Redskins at Giants, 4:15PM
The Redskins and Giants will meet at the Meadowlands on opening week for the second time in two years. Washington head coach Jim Zorn is expected to give quarterback Jason Campbell more opportunities to throw the ball vertically now that Campbell has one full season under his belt in the West Coast Offense. It’ll be interesting to see how he does against a Giants team that can bring a ton of pressure. Albert Haynesworth will make his Redskins debut today, so Giants QB Eli Manning better get the ball out of his hands quickly or else he could be in for a long day. The Giants need someone to step up in the passing game, and maybe it’ll be rookie first round pick Hakeem Nicks.

San Francisco 49ers at Arizona Cardinals, 4:15PM
The defending NFC Champion Cardinals will look to start the 2009 season off on the right foot when they host division rival San Francisco. The 49ers are also looking for a fast start under head coach Mike Singletary, while quarterback Shaun Hill will get the opportunity to show that he can lead this team after winning the job over Alex Smith in the preseason. That said, San Fran will still try and keep the ball moving on the ground with Frank Gore and rookie Glen Coffee after leading the league in rushing yards this preseason. This is an intriguing matchup because while the Cards have a dynamic passing game, the Niners have a solid secondary that might be able to somewhat neutralize receivers Larry Fitzgerald and Anquan Boldin.

Rams at Seahawks, 4:15PM
Two teams with new head coaches square off in Seattle, as Steve Spagnuolo’s Rams will take on Jim Mora’s Seahawks. Matt Hasselbeck is now healthy, which benefits Seattle in its quest to get back on top in the NFC West. The Seahawks must find a running game though, or else they can continue to struggle all season. Receiver T.J. Houshmandzadeh and rookie linebacker Aaron Curry make their debuts for the Seahawks today, while the Rams will start rookie tackle Jason Smith, who was the second overall player taken in April’s draft.
