a moronic thing to do indeed but apart from that moment he had a pretty decent game, so I doubt he was affected by the engagement thing ... had that been the case, I would have expected him to be piss poor altogether.
Brady's pass to WW wasn't a perfect one either albeit definitely catchable. And Brady/the OC also made that stupid play call for the safety, which proved decisive in the end as to what the giants needed on their last drive - because of the safety, 3 pts and killing the clock worked perfectly for them, otherwise they would have needed a TD and been more rushed, make more mistakes, and maybe not get the TD at all.
All in all, can't single out any one player for the loss, as was with Kyle Williams for the 49ers - the Pats lost to a more talented team ... made one costly mistake and failed to make it a 2-possession game when they had their chances ... on top of paying the price of Gronk being pretty useless.
Life happens
