the colts know that their time in the sun is ending, and they have that last push in them.
Manning doesnt roll over, he gets better as the game goes on - and will do the same as the season goes on. by the end of the reg season - i guarantee they are streaking.
while i like the Bucs, they seem more lucky to me then good, and you've gotta need more than luck in the post season.
the steelers are my pick for AFC champs, but the colts will be in the mix at the end.
