Jason Campbell vs. Eagles Pass Rush
Last week, Campbell stared down the Dallas Cowboys' blitz and completed several clutch passes. He gets to stare down another aggressive, blitzing defense in Philadelphia this Sunday.
In the Redskins' 27-17 loss to the Eagles in Week 7, Campbell was sacked six times.
His offensive line has improved in recent weeks with Levi Jones settling in at left tackle and Stephon Heyer shifting back to right tackle. He could have a new right guard in rookie Edwin Williams, though.
The Redskins have allowed 32 sacks this season, 30th most in the league, so pass protection remains a premium for Campbell.
Campbell has a new trio of running backs--Rock Cartwright, Quinton Ganter and Marcus Mason--who must help with blitz recognition and pickups. Campbell's mobility could be a factor--he has 158 rushing yards this season.
The Eagles, tied for second in the league in sacks with 30, like to bring pressure from every direction, but it is their defensive line that gets to the quarterback most often. The line has 24 of the team's 30 sacks.
Redskins Secondary vs. DeSean Jackson
The Redskins' pass defense has thrived on a combination of a strong pass rush and a sound secondary. The unit is ranked No. 1 overall, allowing just 161.6 yards per game.
The pass defense has also allowed a 58.4 completion percentage, eighth-best in the league, and just 10 touchdown passes, sixth-best in the league.
DeAngelo Hall leads the secondary with four interceptions, but his status is questionable heading into the Eagles game. He suffered a sprained knee in last week's game at Dallas.
In Week 7, the Redskins rolled coverage in Jackson's direction and limited his opportunities. Still, Jackson made his presence known with two game-changing plays.
Jackson ran for a 67-yard touchdown on a wide receiver reverse and caught a 57-yard touchdown pass, beating Carlos Rogers.
The Eagles, led by quarterback Donovan McNabb, are ranked 12th in the NFL in passing offense. Jackson has 42 catches for 728 yards--a 17.3 yards-per-carry average--and five touchdowns.
Devin Thomas vs. Eagles Kick Coverage
With Rock Cartwright taking over as the Redskins' primary running back, Devin Thomas steps in on kick returns.
Thomas has three returns for a 25.7-yard average this season, including a 38-yard return to open the second half at Dallas last week.
He was a prolific kick returner at Michigan State, where he was ranked 11th in the nation with a 29.1-yard average in 2007.
The Redskins are ranked 13th in the NFL with a 23.1-yard kick return average. Meantime, the Eagles are in the bottom half of the league--24th overall--allowing 24.3 yards per kick return.
Tracy White, Akeem Jordan, Sean Jones and Moise Fokou lead the Eagles' special teams units in tackles.
Levi Jones vs. Trent Cole
Jones was inserted into the Redskins' starting lineup on Nov. 15 and he has helped solidify the left tackle position.
The 6-5, 307-pounder faced off against two of the NFL's top pass rushers in Denver's Elvis Dumervil and Dallas's DeMarcus Ware and held his own. He yielded one sack to Dumervil and shut out Ware.
In Philadelphia, Jones takes on Cole, a 6-3, 270-pound speed rusher who has posted 8.5 sacks this season and 43 in five years.
Cole matched up with Stephon Heyer in the Redskins-Eagles game at FedExField in Week 7. Cole had two sacks to lead an Eagles pass rush that posted six sacks overall.
