I don't think his arm looked dead I think his OL was letting him get killed. It was almost a free runner coming at him every pass play and that was before the game was out of hand. That is the blueprint to beating a high flying offense, get to the QB. All of Brady's SB losses were to to the pressure he received, same with mahomes against the Bucs, they dominated the Chiefs OL and what did the Chiefs do? Went out and revamped the OL which is exactly what we should do at the end of this season.
