Pat, I agree with a lot of what you said. And no, saying he couldn't win the big one prior to the Super Bowl was not entirely unjustified. The only thing I would have taken issue with was the statement that he lacked the imagination or balls to win it all. Anyone willing to start the second half of the Super Bowl with an onside kick lacks neither. His problem in the past was having substandard QBs who wilted under pressure. Good teams were able to sell out against the run and dare the Steelers to beat them through the air because their Qbs were incapable of doing so. O' Donnell, Stewart, Maddox - all these guys wilted when given the chance to carry the team. Now, for the first time in his tenure, Cowher has a QB he can lean on when necessary (see every AFC playoff game this season.) That was the difference this year.
Give Cowher John Elway and Shanahan Kordell Stewart and see who would have multiple rings now and who would have none. QB play is everything in the playoffs, and it was that shortcoming, not a lack of imagination or balls, that had kept Cowher from the mountaintop all these years. Lest you think this is revisionist history, a search will pull up posts I made to this exact effect prior to the Super Bowl win. Given the tools, Cowher showed why he's as good as anyone.

The AFC is set up for a major run similar to the SF/Dallas/Packers run of the 90's.
The AFC has not had this caliber of teams since Oakland/Miami/Pittsburgh in the 70's.
I would suspect with the resigning of Alexander and most likely resigning of Hutchinson, as well as the rest of the team being pretty young, the Seahawks will be the favorite in the NFC next year.
How do you anoint a favorite in the AFC? Pittsburgh is the defending champ and will only lose Randle-El and Bettis. NE will be getting Harrison back and only lose Givens. Indy loses nobody and was 14-2 last year.
Also, you have Denver doing a bit of retooling and they were 13-3 last year. SD, with a little bit of luck, could have been 13-3 last year. They are letting Brees go however. Cincinnati was 12-4 last year but has the injury to Carson Palmer to contend with. Jacksonville was 12-4 and is an up and coming team. KC is making strides on D but now has Herm Edwards as coach.
Its a good time to be a fan of an AFC team. The competition is tremendous.
