Steelers, for a few reasons:
1. They've kept nearly the whole team. Kimo, Randle El, and Hope are the only ones notable that left, besides Bettis retiring.
2. The Steelers will open up the offense a little more for Ben, but they still pound the ball. Willy Parker has done fine as the starter.
3. All this talk of "oh, only if Ben stays healthy" -- they've proved they can win without him. How about if Carson Palmer gets injured, do you really think the Bengals can win?
4. The defense is still one of the best. Porter is still angry as always, Troy is everywhere, and Ike Taylor is coming about.
Don't get me wrong, the Bengals are a great team. But no matter how well they did last year, that was only one season. And let's stop with the whole "if Kimo didn't fall on him" excuse. One play, a legal hit, and it was obvious that it wasn't intentional to hurt him. It's FOOTBALL. It happens.
I'm excited because I think this will be a tough division. Not just Steelers and Bengals, but from the Ravens as well. And as much as I hate them (Browns) I don't like seeing a team suffer for so long. That organization is cursed. Every #1 pick of theirs has some off-field crap that injures them. Here's to hoping Charlie Frye and the rest of their acquisitions can clean it up.
