I'll be real surprised if Peyton leads the Broncos to a win tomorrow against the Steelers. Of course, I'm prejudiced.
I think Peyton has some good years left if he stays healthy. The AFC West Division should be a dogfight this season. Any one of those four teams, Denver, San Diego, Oakland, or Kansas City could win it. Super Bowl for Denver or any of the other teams in that division is a stretch. There are too many better teams in the AFC like New England in the East, Baltimore and Pittsburgh in the North, and Houston in the South who are going to likely have better records than Denver (or whoever wins the West) and thus home field advantage in the playoffs.
