Sunday’s Best: Redskins (3-1) at Eagles (2-2) 1:00 PM ET FOX
Who would have thought after four weeks that the Washington Redskins would be right in the thick of things in the NFC East? Especially after they bombed in the opener against the defending Super Bowl champion New York Giants. But they are, and a big reason for that is the maturity of QB Jason Campbell, who has looked comfortable running Jim Zorn’s West Coast Offense the past three weeks. But he’ll get a major test this weekend against Jim Johnson’s blitz-happy defense. The WCO is predicated on short timing routes and getting the ball into the hands of receivers so they can get yards after the catch. If Campbell can’t get the ball out of his hands quickly, Philly is sure to produce plenty of sacks and turnovers. Whether or not the Eagle offense converts those turnovers into points remains to be seen, however. In their loss last week to Chicago, Donovan McNabb struggled getting the Eagles into the end zone without the threat of Brian Westbrook in the backfield. Westbrook will be a game time decision, although he has seen a fair about of practice time this week, which might be a good sign that he’ll play. Expect another physical matchup between NFC East rivals.

Upset Watch: Bills (4-0) at Cardinals (2-2), 4:15 PM ET CBS
I’m not fooling oddsmakers by calling this a potential upset because they’ve already established the Cardinals as 1-point favorites. But considering how well the Bills have played this year and how Arizona surrendered 56 points in last weeks loss to the Jets, a Cardinal victory would be an upset. The fact of the matter is that the Cards just flat out play better in the desert than they do on the road. They’re a completely different team and while dynamic wide out Anquan Boldin is not expected to play after suffering a nasal injury last Sunday, the Cards have more than enough offensive weapons to pull out a win. The key will be Kurt Warner not turning the ball over and for the team to play all four quarters. Buffalo has trailed in the second half of three of their four victories this year, which means that they’ve been outstanding in the clutch. Arizona will have to play a complete game to earn a win, but an upset could be in the making.

Intriguing Matchup: Steelers (3-1) at Jaguars (2-2), 8:15 PM ET NBC
The Steelers may be 3-1, but they can’t feel too good about the way things are unraveling as injuries continue to mount. Not only will Pittsburgh go into this game without their top two backs in Willie Parker and Rashard Mendenhall, but Ben Roethlisberger is also dealing with shoulder and hand injuries and OT Kendall Simmons is now lost for the year. The Steelers had offensive line issues coming into the season with Simmons in their lineup. Now they have to play without him, which isn’t good news for Big Ben and the rest of the offense. The Jaguars started the year 0-2 but are now gaining confidence after beating the Colts and Texans in dramatic fashion over the past two weeks. The running game has opened up the passing attack for David Garrard, who is starting to play like the quarterback who led the Jags deep into the playoffs last season. We’re going to see what Pittsburgh is made of, because Jacksonville is starting to show signs of the Super Bowl contender that everyone that they’d be in preseason.

Other Notable Games:
Titans (4-0) at Ravens (2-1), 1:00 PM ET
Tennessee is one of only two teams still undefeated and perhaps is playing the best defense in the AFC. Rookie Joe Flacco looked like he was starting to come into his home against the Steelers, so it’ll be interesting to see how he fares against a tough Titans’ defense.

Buccaneers (3-1) at Broncos (3-1), 4:05 PM ET
This is one of the best matchups on the Week 5 schedule as it pits Monte Kiffin’s defense against the Broncos’ offense, which has been one of the best units in the league so far. Can Denver bounce back from its embarrassing loss to the Chiefs last week? Can the Bucs further convince people that they’re a contender with Brain Griese under center?

Bengals (0-4) at Cowboys (3-1), 4:15 PM ET CBS
Ocho Cinco vs. Grab Your Popcorn. Should be a good one.

SPORTSbyBROOKS.com notes that Baltimore’s Willis McGahee isn’t too fond of NFL sideline reporter Suzy Kolber’s latest work, which had her stating on Monday Night Football that maybe part of the reason why he got hurt against the Steelers was because he missed OTAs this summer.

The CARROLL COUNTY TIMES reports that Willis McGahee didn’t take too kindly to Kolber’s suggestion of why the RB got hurt in the Ravens’ 23-20 loss to the Steelers. McGahee went down in the first half after suffering a bruised rib, and his status is still uncertain for this Sunday’s game against the Titans.

Kolber had reported that McGahee skipped out on almost all of the Ravens’ voluntary organized team actvities, or “OTA’s”, during the offseason – and such an absence may have been to blame for Willis’ wounds.

But McGahee didn’t like hearing that:

“Yeah, that bothers me,” McGahee said. “I’m not here for OTAs, so I get hurt? If I was at OTAs and I got hurt, then it would be, ‘He worked so hard. It’s a shame.’ No, it doesn’t work like that. Things happen in football.

“I got hit in the ribs. Would my ribs have been stronger if I had been at OTAs? I guess I’m not drinking enough milk. I’m very disappointed that once again the reason I got hurt is because of OTAs. That was garbage.”

Hey, watch what you say, Willis – Joe doesn’t like it when you mess with his women. Then again, if McGahee had bothered to practice with his teammates in Baltimore instead of by himself down in South Florida, the subject never would have been brought up in the first place. Don’t blame Suzy for your poor judgment.

I agree with Brooks in that the subject wouldn’t be open for debate had he been with his teammates this summer, but McGahee does have a point. What does a rib injury have to do with him missing OTAs while trying to recover from a knee procedure? And his comment about not drinking enough milk was pretty funny.

Fantasy owners that were hoping to have Brian Westbrook back in their lineups this weekend might have to wait another week or two. According to Brian’s brother Byron, who plays corner for the Redskins, Brian’s ankle injury is more serious than the Eagles are letting on.

“I don’t think he’ll play,” Byron Westbrook said. “The ankle injury is more serious than what the Eagles put out. You know how Andy Reid is about injuries and giving out information. Just watching him on the sidelines after he turned his ankle [against Pittsburgh two weeks ago], it didn’t look good.

“He’s a warrior and it’s an NFC East game and he wants to play, but its also early in the season and it’s not a playoff game. If he goes out and plays at 75 percent, you could end up making it a lot worse. He would want to get to 90 percent to really be able to play.”

Westbrook said he and his big brother, who is getting treatment but, according to the Eagles, is scheduled to practice today, last talked on Sunday.

As he usually does when the Redskins are preparing to face the Eagles, Byron Westbrook will continue to act as his brother on the scout team all week. The Redskins will still prepare in case Brian Westbrook plays.

“We still have to prepare for him regardless,” Byron Westbrook said. “And if he can”t play, then we’ll just be over-prepared.”

Considering that the Redskins play the Eagles this weekend, it’s wise to take Byron’s information with a grain of salt. The two are family, but it’s not like Brian is going to hand out trade secrets to his practice squad brother, who-oh-by-the-way, plays for a division rival. It looks like (Brian) Westbrook will be a game-time decision, but I’m willing to bet he plays considering he practiced some on Wednesday.
