None of which would have happened if he just kneeled like he should have
Doesn't matter, the refs spotted the ball indicating Wisconsin had possession, they then should have made the obvious delay of game call. They committed to one mistake but weren't willing to make the right call after they screwed up. It just looked amateurish at best. Apparently stopping the official from taking the ball is not grounds for a penalty in the PAC-12. Officials don't get the luxury of being excused from failures because a player did something odd.
