Ugly truth. You can also see what led up to it on separate videos. Nacua swung at a player being held back by a coach. The punch bounced off the surprised player, but he reared back and knocked Nacua flat with one punch. Nacua, now bloody and humiliated, really started acting like a street thug on meth running around looking for someone to sucker punch from behind and he did it on national TV. The fact that BYU fans endorse Nacuas actions is truly awful.
