The point being no other time in the NFL has this been called!! Hell the fan in NE also new it was a Fumble!
Your wrong, it was called earlier in the year when the Patriots played the Rams in the regular season. That is why they were pretty confident it was going to be overturned. But, why let the facts get in the way of a good "the NFL is against us" Al Davis conspiracy theory.
BTW, the blow to the helmet is always called, except on that play.
