But can somebody tell me how in the hell new York gets 2 points for a safety without tackling Brady in the end zone ??
Brady didn't have to be tackled because the penalty happened when he was in the end zone. If he wasn't in the end zone it would have been half the distance to the goal. When the quarterback is in the end zone with the ball any penalty against the offense results in a safety- no tackle is necessary.
The same thing happened against San Fransisco . New York fumbled while their running back was still churning his legs and wasn't down yet. The 49ers recovered but the referred called the play dead while the New York running backs knees hadn't touched the ground yet.
That's because the official blew his whistle before the fumble, indicating the play was over. Since the play was officially over there could be no fumble.
