That's what makes sense with the consistency of the play and its aftermath. NRC said the ref told him it was tipped and he said this right after the game. One angle looks like it is tipped AMD in the above posted clip there is another angle right at the beginning that shows Brockers hand is close. So, that's two angles that give the appearance of a possible tip.

Then, as the above video I just referenced, the angle that everyone has seen and commented about, it shows no tip.

If Coleman was truthful and that is what the ref told him, you can't fault the ref if he didn't have the angle that the whole world had from a camera on a platform.

So, if the NFL allows in the future, review of a non call, then all action needs to be fair game: holding, face masks, non lowering of the helmet.
