It looks pretty damning to me. No doubt it was a non-call only a very few (two?) QBs get in that situation.
But to me the even more damning play of Brady was his unwillingness to scramble for the first down (or even TD) on that late 4th down play because he risked getting trucked by Ngata and chose to throw it away instead.
