the explanation is Pac-12 Refs. I’ve watched enough games in other conferences to know that play doesn’t get flagged, even if it was technically the right call. Watch an SEC game and if the players doesn’t get carted off, it’s a no-call because they look at intent.
Bishop absolutely hit a defenseless player in the head/neck area. Bishop also absolutely did everything he could to avoid the contact. Pac-12 refs don’t factor in intent which was supposed to be part of the rule change a couple of years ago. Complaining to the league office isn’t going to get any relief because they are the ones who are telling the refs to call it the way they do.
