Once the whistle blew, which happened when the ball hit the ground, the play is over and it's Iowa's ball. They then called a foul on Iowa which they should have done, and also called a foul on PJ which they should not have done. Tyler was laid out on the ground from the hit and the whistle had blown, a head coach has the right to take the field to check on an injured player. The idea that he checked on him too fast makes no sense, that's not part of the rule book. You can't run onto the field during a live play, but the whistle had blown.
The penalty on PJ didn't make much of a difference in the game, the dropped ball and quick whistle from the refs to end that play did make the difference.
This. It is why I still am struggling with the call. If it is after the play, then how can you penalize a coach for running out to check on his player? Is there a minimum time rule that we are not aware of?
If it's subjective, how can you make that call?
