Honestly, I think the play with Montgomery and #3 for Baylor should have been a no call. Both guys had a hold of the other’s jersey. When u watch it again I think the Baylor dude was trying to slow down as they got to the sideline. The refs should have stepped in and immediately calmed everybody down. There should not have been a penalty called. Then #31 started taunting and that was not called and should have been. Then the play with the DB and Butler never should have gotten to that point. Poor officiating led to the melee. Suspend the officials for a game.
After Montgomery was out of bounds he had plenty of opportunity to let him go. but choose to drive him into the drink cart 12 yards out of bounds. No idea what you were looking at.
