The immediate supension, pending review is a long standing Athletic Department rule...
Rhoads could have pulled this out of the KF playbook "I'm aware of this alleged incident since (insert date) and consider it to be a serious situation. Based on what I know to this point, I think it's best to let due process run it's course before coming to any judgement"
So because Rhoads didn't say that, and the Athletic Department and "senior-level" ISU officials said it for him makes this different...how?
