I think it's a bit too early to declare the Patriot's dynasty dead, but it's at least badly injured. Belichik will fill the football world in on Brady's status at 3:00 PM EST in what I imagine will be as grumpy and cryptic a fashion as he can muster. Official Patriot's Fan Friend, Huginn, reports that the Pats may be trying to acquire Chris Simms in an effort to salvage the season, though he'd like to see them trade for Rex Grossman.
As a "good sport" Colts fan I am officially obligated to express my sympathies for the Patriot's organization and mention that I wish Brady were healthy so that we could beat them at full strength. If that reads disingenuous, just consider that it's only exactly as disingenuous as when Bill Simmons wrote something similar about the Colts, though, on that occasion, it was within the context of claiming that the Colts were banged up on purpose and that they were cruelly "cheating" the Patriots. I hate that bastard.
