I'm picking my Steelers (of course) to go to the playoffs, and possibly further. While I'm not going to try and call Super Bowl teams yet, I do believe they'll reclaim their place at the top of the AFC North. I think they have the talent to do it; hopefully they can establish a solid running game to compliment Ben's abilities, and they can fix the problems on defense.
Also in the AFC, I expect the Jets and Texans to be contenders, as well as the usual staples like the Chargers, Colts and Pats.
On the NFC side, I figure Arizona will take a dive. San Fran will make the playoffs. Maybe Chicago too, if they can figure out how to use Cutler more effectively.
I expect the Saints to make the playoffs again, as well as the Packer and Cowboys. I think that the NFC title game will be between New Orleans and Green Bay. I'd be happy with either of them making it to the Super Bowl. I have a feeling the Eagles will struggle, though. This season didn't end well for them and there are a lot of questions now as to what will happen at the QB position.
And then there's the Vikes. With Favre, they make the playoffs and are a serious Super Bowl contender. Without him, they might still make the post season, but won't get far.
Other predictions... the Ravens will be mediocre as the defense continues to age and Flacco continues to show that he's not quite the "elite" QB they wanted him to be. Chris Johnson's status as The Next Barry Sanders will become more evident as he sets a rushing record while his team goes 8-8. The Bengals will reclaim their Bungle status. Detroit will win a good number of games, but fall short of the post season.
And JaMarcus Russell will throw for 1 TD and 19 interceptions before they bench him after the FOURTH game.
