Apart from having to deal with ignorant, fanatical Tebow bandwagoners, this actually should prove far less eventful than you might hope. Nothing kills drama faster than Belichick's hoodie, and it's not like anyone will be clamoring to replace Brady with Tebow (at least no one who cares about the Pats). If you really wanted to see a locker room Teblowsion, you needed to watch the Drama Queens - I mean, Jets - last year. Additionally, I believe Tebow understands that he's not coming to NE to be the primary QB. The hoodie signed him because he recognized Tebow's motor and team drive, and because his stock was much lower post-Rex.
Of course, Chick's also probably pulling a bit of an F-U to the rest of the league. It's part of his hoodiness.
