Trying to get information out of the Patriots is like trying to pull the ship out of a ship in a bottle. Even if you do get anything out, it will be broken up bits, and essentially worthless.
The Patriots are conceding that Brady has a sore right shoulder. They seem to be implying that he won't play in Thursday night's preseason finale against the Giants. Bill Belichick stated:
"I’m saying that we made the decision to play other quarterbacks in the second half of the Washington game because we wanted to see them play, and that will be the same situation [in] the Giants game. Tom had a desire to play, but we made a football decision to play other players because I think we need to see other players at that position and make an evaluation there."
Brady has 15 days to recover from whatever the hell is wrong with his shoulder. I doubt there is any tear, or even strain. I'm not too worried about it.
