I like Brock, so I'd like to see him take over, but if Peyton comes back, I don't see that happening.
I'm hoping Manning does retire, and in the process retires as a Colt. He owes it to the fans here, since he spent his prime in blue and white, and had all the MVP's, the SB, and I believe it's worth him going out as a Colt, since he introduced a new younger generation of football fans to the fold.
I would hate to see him return at age 40 like Favre did and go out with a horrific injury. Watching Favre in 2010 was depressing and how it all ended was a real heart break.
You and I are on the same page with the Steelers. I think if they would have got past Denver, they would have given New England a tough game with Brown coming back. Pittsburgh probably wins the AFC this year, if they could have just got past Denver, and they turned out to be the one team that played them the toughest in all of the playoffs. I like Pittsburgh's chances next year of representing the AFC, if they can adjust their secondary a bit, which I do expect to improve over time.
