Wild card weekend graduated four teams -- the Chargers, Ravens, Cardinals, and Eagles.  Can any of these teams make noise against the well-rested one and two seeds?  Let's take each candidate one-by-one.

Chargers at Steelers - San Diego entered the playoffs with an underachieving 8-8 record.  Tomlinson is missing playoff action due to a serious groin injury, and the Charger D doesn't have the same bite as it did when Merriman was rushing opposing QB's.  If Denver doesn't trip over its own two feet the last month of the season, San Diego and Norv Turner are watching the playoffs from their respective living rooms.  Yet, San Diego somehow managed to beat the red hot Colts, and Phillip Rivers is becoming one of the league's top passers.

This weekend, the Steelers defense should be able to stop Sproles and defend San Diego's average receivers.  Pittsburgh's weakness is attrocious pass protection -- and a few dangerous pass rushers could blow up the Burgh's Super Bowl aspirations.  Lucky for Pittsburgh, the Chargers defenders do not produce any kind of pressure.  San Diego will be one and done.

Ravens at Titans -  The Ravens flock into the new year with the same baggage they have carried for the last decade -- an offense that doesn't scare anyone.  But Joe Flacco may finally be the bird of a different color.  He showed some rookie inconsistency in yesterday's game against the Dolphins, but he also made some big time NFL throws.  He's far more dangerous than Kyle Boller or a Steve McNair at the end of his career; that's for sure.

When Baltimore swoops into Tennessee, they are facing a bad matchup.  Baltimore plays physical - so do the Titans.  Baltimore like to run the ball - the Titans can stop the run.  Baltimore has a rookie QB - the Titans excel at dropping defenders into coverage and intercepting passes.  The teams are very similar, actually, but there are two key differences.  One, Kerry Collins is experienced and won't rattle easy, while Joe Flacco is still an untested rookie.  Sorry Joe, but the Titans D is not the Dolphins D.  Two, Chris Johnson and LenDale White are better than the Ravens running backs. 

The Ravens are fighting an uphill battle here, but this should be a tight, low-scoring game ... and in close games, anything can happen.

Cardinals at Panthers -  Many fans were waiting for the Cardinals to remember they were Cardinals and subsequently self-destuct.  Their recent blowout loss at New England was as good a reminder as any.  Yet, the Cards played an inspired, physical game to overtake the Falcons on Saturday. 

When they roll into Carolina, their offense should still be able to score, but look for Kurt Warner to face considerably more pressure.  A mistake or two from Warner may be all the Panthers need to attain a lead and run the ball thirty times.  Don't bank on an Arizona victory.

Eagles at Giants -  Is there a more dangerous #6 seed than Philly?  Not in this year's playoffs.  Philly is hot and their defense is causing turmoil -- a combination that helped the '06 Steelers and '07 Giants earn Super Bowl rings.  The Eagles could be next on that list.

Six weeks ago, I would have taken the Giants over any team in football, but the loss of Plaxico, an injury to Brandon Jacobs, and a waning of momentum has slowed Tom Coughlin's march to repeat.  Monster back Brandon Jacobs is back for this big game, but the Giants as a whole might struggle to get off their flat feet and sound the alarm for battle stations.

These two divisional foes know each other well, making it all the more scary for Giants fans.  If there is any upset this weekend, look for it here, at the hands of Andy Reid's Eagles.
