with his helmet in hand smacking players on the other team. But I did see Memphis players doing that.
I did see Nacua, with a swollen and cut face from being punched or smacked with a M helmet punching a Memphis player, who had no helmet on and may well have been the one who smacked Nacua with that helmet or his fists. I'll forgive Nacua for the retaliation. He was, after-all, provoked. He didn't start it, as demonstrated by the damage on his face.
Let's don't be jerks and blame BYU players when we don't know if any are actually at fault.
