Uh BYU didn't score after the Blechen hit (you are insane if you think that wasn't a PF and it would have looked like he led with his head in slow motion because Mahina's head jarred backwards and penalties aren't reviewed), which if not called still would have resulted in a catch. He caught the ball and the ground caused the fumble. They gained more than 15 yards on that play. Wide wasn't horse collared.
You are going to whine about holding. That is a steep cliff with all the holding that goes on during a game and all the holding Ute DBs get away with every year.
What PI calls in 2006. There were none on the last drive in 2006.
