This right here, 100% correct. It's like the same thing in football when the DBs get too handsy and hold a lot or on every play thinking the officials won't want to call it that much. Some officials will call it every time.ISU plays defense by daring the officials to call a foul on every possession. The officials took them up on it.
They need to learn how to play defense with the same intensity without fouling.
ISU needs to learn this and if they have some statistical information on certain officials before the game they should use that. I don't know if teams get that info before the game or if they only find out who is officiating right then and there when the game starts.
