Redskins RB Alfred Morris vs. Seahawks MLB Bobby Wagner -- This battle of two rookies will be fun to watch. Morris has had an amazing season, while Wagner might be the Defensive Rookie of the Year. He has to get Morris before he can get going on those read-option plays.
Seahawks C Max Unger vs. Redskins NT Barry Cofield -- If the Redskins are to control Marshawn Lynch, it will have to be with Cofield having a good game on the nose. He has played well the last eight weeks, but Unger is one of the league's top centers. He has to get movement on Cofield if Lynch is to get the running game going. Unger had a good game on Cofield in 2011.
Bengals RG Kevin Zeitler vs. Texans T J.J. Watt -- These two former Wisconsin players will be in a battle all day. Zeitler has had a good rookie season, but this is a huge test for him. Watt is the best defensive player in the league.
Redskins LT Trent Williams vs. Seahawks RDE Chris Clemons -- Clemons is one of the most underrated edge rushers in the league. Williams had a Pro Bowl season and is a big reason why RGIII gets to run the read-option so well. But Williams has to keep Clemons off his quarterback.
Colts OLB Robert Mathis vs. Ravens T Kelechi Osemele -- Mathis is going to the Pro Bowl as an outside linebacker. Osemele is a rookie who will be making his first playoff start. Osemele has to handle Mathis if Joe Flacco is to make plays down the field.
Colts WR Reggie Wayne vs. Ravens CB Cary Williams -- When Lardarius Webb went down with an injury, the Ravens lost their best cover player. But Williams has stepped up and done a solid job. Wayne is a smart, veteran receiver who knows all the tricks. This will be a tough battle if Williams is on him in single coverage.
Texans G Ben Jones vs. Bengals DT Geno Atkins -- Atkins has been a force all season inside. He is strong, fast, quick, can rush the passer and play the run. Jones has had some problems lately and might be spelled some by rookie Brandon Brooks.
Bengals WR A.J. Green vs. Texans CB Johnathan Joseph -- The Texans have had big problems with the pass. They play a lot of man coverage, which leads to big plays. Green will likely see a lot of double, though, but I would imagine that Joseph, a former Bengals player, would be on him in man some.
Vikings LT Matt Kalil vs. Packers OLB Clay Matthews -- These two former Southern Cal players had a nice battle last week. Matthews got one sack, coming all the way around the back side to chase down Christian Ponder. But Kalil did a nice job on him for much of the game.
Vikings DE Jared Allen vs. Packers LT Marshall Newhouse -- Allen had a sack last week, but it came on an inside move against guard T.J. Lang. Newhouse did a nice job on Allen when he locked up man on man. Allen seems to get sacks in bunches, so Newhouse has to keep him off Christian Ponder.
