I was also in attendance at the TBFOC.
To overturn a 9-1-4 ejection, IR is supposed to consider the same to questions:
1. Was the player defenseless by rule?
2. Was there contact to the head or neck area?
If the answer to either is NO, then they can overturn. There is to be no consideration of intent or degree. They really do want it to be that simple. The NCAA is trying to be out in front of taking the head out of football. They are of the opinion that we won't have a game in 10 years if we're unsuccessful in taking the head out of it.
The mantra at the clinic was VERY simple:
Was the player defenseless? Yes.
Was there (any) contact to the head? Yes.
He's gone.
Edit:
Under the new penalty, both hits would have resulted in ejections this year. Both would have been upheld by replay. The second may have resulted in additional time off if I read the tea leaves correctly.
