It was the reviews, it was Vernon (and other Duke WR) pushing off all day, it was a 50/50 late hit call on DP on a 4th down play. There were a couple of others as well, just can't remember them right now.
And the phantom facemask after the DP roughing the passer....come on. It was so bad. I was convinced they were going to come up with a way to give Duke the ball on the onside kick.
