Three keys to an Eagles win

1. Brace for RGIII: Robert Griffin missed last week's game against the Browns with a knee injury, but he has been cleared to start against the Birds. The Rookie of the Year candidate burned the Eagles for 200 yards and four touchdowns in a 31-6 beatdown in the first matchup between the teams this season.

2. Let Foles loose: The Redskins' passing defense is one of the league's worst, ranking 30th, allowing 285 yards per game. This game will go a long way in determining whether Nick Foles can be the quarterback of the future going forward.

3. Don't overuse Brown: Bryce Brown, still dealing with ballhandling issue, is going up against a top-10 run defense, which allowed only 80 combined rushing yards between Brown and LeSean McCoy in the teams' first matchup this season.

Spotlight on ... King Dunlap

Position: Offensive tackle

Height/Weight: 6-9/330

Age: 27

Birthdate: Sept. 14, 1985

Hometown: Nashville, Tenn.

College: Auburn

Acquired: Seventh-round pick of Eagles in 2008 draft (230th overall)

Did you know? Both of Dunlap's parents were athletes at Tennessee State; King IV was a defensive tackle taken in the fifth round of the 1969 NFL draft by the Baltimore Colts, while Robin was a track star.

Who's Hot

Brandon Graham

One of the few bright spots on the defensive line ended up with 2.5 sacks against the Bengals and now has 5.5 on the season, tied for most with Fletcher Cox and recently released Jason Babin.

Evan Mathis

The only original starter left on the offensive line did a great job on Bengals defensive tackle Geno Atkins, not allowing a sack to the Georgia product who has 10.5 sacks on the year.

Who's Not

Dominique Rodgers-Cromartie

The Kevin Kolb trade really hasn't worked out for either the Eagles or Cardinals. DRC continues to struggle against opposing wide receivers, highlighted by missing a ball that could have been easily intercepted. It ended up in the hands of Bengals wide receiver A.J. Green early in the first quarter.

Bryce Brown

The rookie running back (above) has shown flashes of brilliance in prior weeks, but continues to struggle with holding on to the football. Brown never had full possession on the fumble returned for a touchdown, which gave Bengals defensive tackle Pat Sims a good shot that jarred the ball loose.

Obscure stat

The last time the Redskins swept the season series was in 2008, behind wins of six points (at FedEx Field) and seven points (at Lincoln Financial Field), respectively.
