I'd say maybe the Seahawks, I didn't expect them to be this bad. Maybe the Jaguars.
I'd probably vote Falcons, as I didn't expect them to turn it around so quickly, but I'm not sure that I'm too surprised since they were able to get rid of Hall and then Petrino and Vick obviously weren't around anymore. I was surprised that Turner is as good as people have said (I was expecting him to flop after everytime they mentioned him they said he could be a starter pretty much anywhere else). I really am not that surprised about Miami since they also were able to get rid of a lot of their baggage and Parcells wasn't hampered by Jerry Jones.
The Jets are about where I thought they would be. I think this has been coming for a while for the Chargers. The coaches leaving (which led to Marty getting fired) and LT wasn't going to be superman forever. Rivers is ok, but he's no Drew Brees either. The Browns, well did anyone honestly think they were seriously going to contend? The Cardinals are reaping the benefits of playing in a very poor division and also a resurgent Kurt Warner (who again has some receivers worth using).
Hmm, actually, it is the Giants for me. I still just don't know how they made the Super Bowl last year, and I didn't think they'd be where they are now, let alone after losing Strahan and Osi.
I guess you could say there's been quite a bit of surprises this year.
