I don't know, that's why I'm asking.
I asked myself and what I came up with was that he loves playing for BB. That's all I could think of. Let's face it, the team doesn't win anymore. Plus all of his buddies have retired or have been dealt. Don't you think that Brady could walk into Krafts' office and say "I wanna talk about a new deal". Why has he let his deal run itself into the final year?
I hope he does because this team needs TB first and fore most!
