As a guy who once lived in Boston for a period of time, I learned one important thing. Never, EVER, get caught wearing a Yankees hat, particularly if you're the starting QB of the Patriots. But that happened to Brady recently, as he strolled down a NYC street with Gisele.
Now, Brady is a huge Yanks fan (Why, I have no idea, he should be a Giants fan since he's from where dwyermaker and I grew up) but this is inexcusable. You just don't do stuff like this when you're one of the faces of Boston. Interestingly, Brady used to wear a Yanks hat in the Patriots locker room until some other players told him to take it the hell off.
Now, this story will vanish as soon as Brady throws his first touchdown pass to Randy Moss, but for at least the next few days, I think Boston needs to be on a suicide watch.
