Brett Favre is almost certainly finished with the Jets, though if he goes to a team like the Vikings next year, that would be interesting. If they could get home field in the playoffs, that would be VERY interesting, because they would play in a dome. However, notwithstanding his past success at Green Bay, he is now no longer effective in cold weather, which explains the Jets' late-season collapse (and the Packers' playoff collapse last year). He single-handedly ended the Jets' season with his abysmal performance against Miami, and he single-handedly cost the Packers a trip to the Super Bowl with his abysmal performance against the Giants last year.
In contrast, anyone who doesn't think Peyton Manning deserved the league MVP this year doesn't understand football. (That TD pass to Wayne last weekend was fucking brilliant.) And anyone who thinks Joe Flacco(!) was more deserving REALLY doesn't understand football. Manning willed the Colts to a remarkable 12-4 record, including a couple of victories in which he almost single-handedly won the game, despite being injured and not having any semblance of a running game. Probably his second best season ever, other than the one in which he set the passing records (since broken by Brady).
My picks for this weekend: Carolina, Eagles, Steelers and Ravens.
Steelers will win the Super Bowl, because they have the best defense. On that note, consider that the Defensive Player of the Year Award was just given to a player (James Harrison) who was undrafted out of college and was cut four times before being given a chance in Pittsburgh. Persistence pays!
