Broncos corner Champ Bailey vs. Steelers receivers Mike Wallace and Antonio Brown -- Wallace and Brown can fly. Both have big-play ability. But Bailey is one of the best man-cover players in the NFL. Who does he take? I would imagine he would be on Wallace, but he might also spend some time on Brown. This is a battle between a smart veteran corner and two young speedy receivers.
Saints guards Carl Nicks and Jahri Evans vs. Lions defensive tackle Ndamukong Suh -- Evans has already come out and said Suh does some dirty things on the field. That should stoke this fire a bit. Green Bay's Josh Sitton dominated Suh last week and these two guards are in that class. Suh didn't play in the first meeting when he served a suspension, so this should be fun. To get pressure on Drew Brees, it has to come up the middle since Brees he gets the ball out so fast. That means Suh.
Giants left tackle David Diehl vs. Falcons defensive end John Abraham -- Diehl has struggled at times this season, while Abraham has come on lately. He was bothered by a groin injury earlier this season, but he's healthy now. And it's showing up. The Falcons have moved Abraham around some, so he will line up opposite Kareem McKenzie some, but I imagine he will be over Diehl a bunch.
Broncos quarterback Tim Tebow vs. Steelers defensive coordinator Dick LeBeau -- The Steelers coordinator is one of the best ever. He has a way of devising schemes to stop different offenses. I expect him to come up with a good one to force Tebow to throw the football. The Steelers will likely play a lot of man coverage and drop Troy Polamalu down in the box. That will force Tebow to throw it. Can he?
Falcons right tackle Tyson Clabo vs. Giants defensive end Jason Pierre-Paul -- Clabo is a classic self-made player, a mauler who pushes the envelope when it comes to dirty play. Pierre-Paul is an athletic freak who was my pick as the Defensive Player of the Year. Does the mauler win? Or does the special athlete win? This will be fun to watch.
Saints defensive end Will Smith vs. Lions left tackle Jeff Backus -- Smith is the Saints best pass rusher, while Backus is a veteran tackle who has to protect Matt Stafford's backside. Smith isn't as explosive as he once was, but he can still get after the passer. Backus has had trouble with good ends at times this season.
Lions receiver Calvin Johnson vs. Saints corners Jabari Greer and Tracy Porter -- How do you stop Johnson? You don't. You just try and contain him. Green and Porter are good cover players, but I would think the Saints will give them help over the top. The Saints limited him to six catches and 69 yards in the first meeting. Earlier this season, Green Bay's Tramon Williams did a good job on Johnson but he got the better of the Packers last week. This is big challenge for the Saints corners. Johnson has been on fire.
Steelers outside linebacker James Harrison vs. Broncos left tackle Ryan Clady -- Clady is a good left tackle who has improved as the season moved along, looking more like the 2009 Clady. Harrison is back after missing time with the broken orbital bone and remains a top-level pass rusher. He seems to really excel in the playoffs. Look for Harrison to set the edge to keep Tebow from getting outside the pocket.
Broncos center J.D. Walton vs. Steelers nose tackle Casey Hampton -- If the Broncos want to get their spread-option going, they have to handle Hampton. That means Walton has to get inside push to allow the guards to get out on the inside linebackers. Walton had a tough go of it last week against the Chiefs, which is why Denver didn't run it as well. He has to play better here.
Bengals receiver A.J. Green vs. Texans cornerback Johnathan Joseph -- Joseph gets a chance to face his former team for the second time this season. The first time, the Texans held Green to five catches for 59 yards as Joseph did a nice job on him. I would imagine the Texans would put Joseph on Green a lot again in man coverage. Green has a size advantage, so that could play out in the Red Zone.
