How the mighty have fallen.

Tom Brady injured his knee in the Patriots' game vs. Kansas City today at home in Gillette. While there's nothing official so far from the Patriot management, early rumors have Brady out for the rest of the season.

Needless to say, this is a devastating blow to the Patriots' Super Bowl hopes after being upset by the New York Giants 17-14. Say whatever you want about how "the Patriots still have Randy Moss, Wes Welker, Lawrence Maroney, and a solid defense," but Brady, like Peyton Manning, is what the organization is built around. If Jim Sorgi can't win with the Colts, then Matt Cassell is definitely not going to be winning with the Patriots.

This also throws the AFC East wide open. If "most improved" awards meant anything, the AFC East would win that particular award. The Jets are widely considered playoff contenders with several major additions in free agency. The Bills made a strong statement in week 1 with their resounding victory over the Seahawks. The Dolphins should at least double their win total from last year.

I would look forward to the Belichick press conference, but I know how it's going to go. "Obviously losing a player like Tom puts us in a difficult situation, but we'll just work through it and concentrate on winning games." Ok Bill. That just got a heck of a lot harder. Looks like the Patriots should have taken a little bit of a closer look at their backup situation during the preseason.

Update: It's official, Tom Brady was put on IR with a torn ACL.
