I don't know that there's anything at Briarcrest other than learning Freeze is just weird. Nothing stands out in the rumors other than him not having any self-awareness that he was making others uncomfortable.
That said, Fulmer has always treated women with respect and expected others to treat women well. I have a cousin who was a hostess back in the day (not a Kiffin hostess) and one of the recruits got handsy with one of the hostesses. Fulmer immediately ended the kids visit and sent him home. So if there was something to the Briarcrest stuff other than what's already out it wouldn't surprise me at all that he'd nix it. At the same time, I'd question why on Earth he'd let it get as far as an on campus interview.
