huh? Colts?
I'm the least confident about them winning. Yes, them playing in so many close games this year helps them, but they did what they normally do when things get locked up. Every time they did that, they flamed out in their first game. The only thing they have going for them is that they cannot play the Patriots in the divisional round.

If they play against the Jets, they'll be against a team with a four-game winning streak. If they play the Ravens, they go against a QB that knows how to win in the playoffs, even if their defense isn't the same. If they go against the Bengals, Carson Palmer has the ability to rip them apart, though that likely won't happen.
The Saints aren't in any better a position, cause they haven't won since December 13. Momentum is very much against them.
The Vikings suddenly couldn't win a road game, and finished at .500 on the road. Their defense is also in shambles, because of the loss of EJ Henderson.
The Chargers play down to their competition, they have all decade. It hadn't mattered if it was Marty Ball or Norv at the helm, they yap more than they play.
The Patriots can't win a road game, and they'll have to go on the road if they beat the Ravens. Losing Wes Welker only adds to the problem.
The Cowboys haven't won a playoff game in 13 years, and have historically laid down in December in that span. They look dangerous this year, but they also looked dangerous when they were the number 1 seed a couple years ago.
The Bengals sometimes have an identity crisis, and don't know how to play offense.
The Eagles have not shown up to multiple games this year, and both games would have greatly helped them for playoff position.
The Cardinals lay down when the going gets rough. They need to play with the lead.
The Ravens aren't as good defensively as they were a year ago. Perhaps it's the loss of Rexy to the Jets, perhaps it's the loss of a bunch of players to the Jets in free agency, we don't know.
The Packers are on fire, but still have a questionable O-line. They haven't gone against a great pass rush in 4 weeks, so we'll see if that still holds up.
The Jets have a rookie quarterback. Historically that is a bad omen, Joe Flacco was the exception. They have a great rush attack and a great defense, but if they put it on Sanchez's shoulder, they will lose.
Despite all of that, all of them could win.
