It wouldn't surprise me if the ref (s) had money on this game. Not only did they let the ASU defenders sit on the ball for many precious seconds, they didn't even bother reviewing anything. The field goal attempt would have been a glorified extra point, too. If this happened farther from the endzone, it wouldn't be such a big deal.
I don't fault the QB at all...he ran to a spot...took a knee...and put the ball right there so the ref could spot it quickly and then they could line up and spike it. It all ran amuck when the ASU defenders jumped on the ball (which I do NOT blame them for either...even if a whistle blew, instinct tells you to jump on it). At that point, the refs have to gain control, and they didn't.
