I agree and pass interference is NEVER called on a jump ball Hail Mary in the end zone!
Well, that statement is definitely off the mark.
If that were true, and I were an OC, I would have 1 primary receiver and 3 or 4 “clearers”. send the cleerers into the endzone to tackle, trip, sweep, push all the defenders to the ground, leaving my receiver to catch the ball unmolested.
The push was obvious, the defender was in position to make a play, and it happened right in front of the official. A blatant violation that was rewarded, and thereby erodes the credibility of the product.
