If you read through this thread you will find evidence of witnesses to Prohm saying to foul.
Prohm's plans and his offensive identity are questionable, but the last ten seconds of this game probably look way better for him if his players listen.
Do you realize how much of coaching is getting your players to do what you tell them to? These are his players that he recruited here. If they don't follow his direction that is 100% on him.
