How many guys was he clustered around? That DB had no chance to get in the back of the end zone. And if Tate didn't blatantly cheat and give him a two hand push in the back that was worthy of whiplash, that DB would have been in the best position of all the players to make a play on the ball. That was the worst offensive pass interference I've ever seen that wasn't called, at least as far as I can recall. And given the circumstances just about every set of eyeballs was looking right there- it's mystifying how no offensive PI was called on that play.
