More often than not, refs give a warning to the players first. As far as I could see, Hill got no such warning, and that ref was ready and willing to pull the flag, just as he did all night.
A drive or two later, Wyoming had a big play down field. The receiver stood over our defender who was on the ground, clearly said something in a mocking way, then did a little dance and a first down gesture right in his face.
It’s one thing if they’re calling it both ways. Last night, they called it only one way, and it was obvious.
