I agree. This kid is clearly emotional and takes things too personal. It’s a good thing to assume responsibility as a leader but not so good if you're viewed as too emotional (there's no crying in football).
Bill is clearly trying to protect him by not allowing him to go to the field in that state of mind. Contrast that with Wilson last week, who got destroyed yet was in the middle of the field with a big smile and chuckling with the rest of the players.
Even in his presser, Mac said all the standard Patriots rap about execution, blah, blah, but didn't sound very confident.
