Redskins' Offensive Line vs. Broncos Pass Rush
For the Redskins, the offensive line reshuffling continues this week with Levi Jones taking over at left guard and Stephon Heyer going back to right tackle. On Thursday, there were indications that Chad Rinehart would start at right guard, replacing Will Montgomery.
New faces in new places have not helped the offensive line develop cohesion in pass protection.
Jason Campbell has been sacked 25 times this season, 29th worst in the league, and 11 times in the last two games. He was sacked five times in the first half of last Sunday's 31-17 loss to the Atlanta Falcons.
The offensive line needs to come together quickly against an aggressive Broncos 3-4 defense.
Denver's defense is ranked third overall in the NFL and seventh in pass defense. When it comes to pressuring the quarterback, the Broncos have posted 26 sacks, third-most in the league.
Linebacker/defensive end Elvis Dumervil lines up against Jones, making his first Redskins start, in one of the game's key matchups.
Dumervil leads the Broncos with 10.5 sacks. Since entering the league in 2006, Dumervil has established himself as one of the game's top pass rushers. He has 36.5 career sacks, fifth-most in NFL in that span.
Redskins Pass Defense vs. Brandon Marshall
The Redskins have struggled stopping the run this year, but pass defense continues to be one of the bright spots.
The secondary is ranked first in the NFL in that category, allowing just 159.9 yards per game.
DeAngelo Hall, who leads the team with three interceptions, and Carlos Rogers are solid in pass coverage, and LaRon Landry serves as the last line of defense.
They face a challenge in Marshall, who Redskins defensive assistant compared to Terrell Owens this week. He is 6-4 and 230 pounds, moves his body well among defenders and has good speed when he gets in the open field.
Marshall leads the Broncos with 44 catches for 468 yards and four touchdowns this season. He has posted 104 and 102 receptions each of the last two years.
Redskins Kick Coverage vs. Eddie Royal
The Redskins' special teams are ranked second in the NFL in kick coverage, allowing 19.9 yards per return, and sixth in punt coverage, allowing 6.0 yards per return.
H.B. Blades, who has returned to action despite undergoing arthroscopic knee surgery on Oct. 27, leads the special teams with 19 tackles.
The Broncos are ranked 23rd in kick returns and 10th in pass returns, but the dynamic Royal is one of the league's top return specialists. He is averaging 23.7 yards per kick return and 11.6 yards per punt return this season.
Royal, who was born in Alexandria, Va., and went to high school in nearby Chantilly, Va., has a 93-yard kickoff return for a touchdown and a 71-yard punt return for a touchdown this season.
Santana Moss vs. Champ Bailey
Surprisingly, Moss and Bailey have competed against each other just once in their pro careers--the 2003 regular season opener when Moss was with the New York Jets and Bailey was with the Redskins.
They typically line up on opposite sides of the field, so they may not match up on Sunday, either. But with Clinton Portis and Chris Cooley sidelined, Moss becomes the Redskins' most dangerous offensive weapon and Bailey may be assigned to him at times.
Moss leads the Redskins with 33 catches for 500 yards, and 15.2 yards per catch average. He has 57- and 59-yard touchdown catches this season.
Bailey is fourth on the Redskins in tackles with 44 and has just one interception and eight passes defended. Last Monday vs. Pittsburgh, he was beaten by fleet-footed Santonio Holmes on a 35-yard pass play to set up a Steelers score.
