I saw HCMM push him back too, but the guy also clearly should have gone back on his own, he kept intentionally getting right up behind HCMM when he knew HCMM was pissed.
That being said, here is my take on things. Doesn't matter what the assistant coach did, whatever it was, it was about as wrong as anything a coach can do. Why? Simple, the kids had been fighting hard, very hard. It was becoming obvious they were outmatched but the kids were still fighting, which meant they had a chance. Momentum was turning towards OU and then a coach goes out there and puts his kids in a terrible position by putting Oregon in the red zone. There is never an excuse for an assistant coach to get a unsportsmanlike call on him...and in this case it was like putting a dagger in his own kids. Therefore, I was glad HCMM went off on him, even if it was in the wrong place at the wrong time and even if he did cross some lines by pushing him back.
