Don't tease me with this title. If Brady only tore is MCL, I'd probably go do cart wheels in the office. By all accounts, its ACL at worst, MCL as well is possible, and god forbid, its that triad they talk about where the meniscus is F'd, too.
Now, let me detach myself from my Brady mancrush for one second: Matt Cassel is the starting QB for the Patriots. We'll take it one game at a time and see how he does. He passed his first test yesterday and then some. He is good enough to take this team - that, by the way, is stocked with a lot of Pro Bowl level talent - and bring them to the postseason.
From there, anything can happen. I just feel bad for Tom mostly today, and I think it'll take some time before I can really get back into thinking about the games, how we'll fare, etc.
