I watched the Rams absolutely dismantle Denver last year. Their defense might be #1 this year, especially if Donald takes a second year leap.
Denver's taken a step back, and if Manning is where he ended up last year, they'll be lucky to win their division. KC and San Diego could both eclipse them. Ware is a year older and was terrible in the 2nd half of the season last year. Talib stayed healthy last year, but we'll see if that holds. Pot Roast, JT and Welker are gone...AND they've got a completely new coaching staff. I think their window has closed, unless Manning really was quite hurt.
Baltimore has taken a step back, too, losing lots of key pieces, but I'll expect them around because Ozzie knows how to put new pieces together as well as anyone (he's right there with BB in this regard).
Pittsburgh was overrated last year. The only reason they're on the list is because it's Pittsburgh and tradition and stuff (and half of the sports shows are stacked with former Steelers!).
If Indy played St. Louis on a neutral field, Luck might leave in an ambulance.
Detroit lost the interior of their DL and the guy who gave them swagger. I doubt they make the playoffs this year.
Green Bay - yep, here I'll agree.
Do not undersell St. Louis. They could contend for the West if Foles can play anywhere near where he was a couple of years ago, and NOBODY wants to play them.
