Like before you made it in the stadium they were great. Once you crossed into the stadium however they flipped a switch and were Mormon bashing jerks. We went to the game in 2018 and we weren't heckled at all before or after the game but we sure were inside the stadium. On the way home we even talked to a group of AZ fans the whole way back to the car. They were actually really nice and complimentary of BYU.
