Who agreed Tate is on the bubble? Certainly not Belichick. The fact that Tate didn't play Thrusday night is a good sign that his roster spot is locked. Pretty much all of the healthy scratches for veterans on Thursday night were players who already had jobs locked up. It is safe to assume Tate is one of them.
You are aware Tate is hurt and not practicing. That is why he didn't play not because BB was lumping him in with Brady, Branch, Welker, and Wilfork as locks for the team?
Or do you consider Josh Barrett a lock for the 53 since he was held out?
