First off, from reading your last paragraph, I'd say you've already passed judgment.
Second, he was bound by a nondisclosure agreement from the 1996-97 lawsuit Naughright brought against the University. He broke that nondisclosure agreement when he wrote his book a few years. I haven't read the book but from what I heard yesterday, he didn't actually mention her name when briefly recounting what happened. Just said what happened from his perspective and said the trainer had a filthy mouth. So a quick question....if it was more than what he said, was actually what she later changed her story to, had already been settled and done with, why in the world would he dredge the story back up which would ultimately only cause him and his reputation harm? Doesn't make sense. If he felt like he got off easy or gotten away with something because what was a much more serious incident was only written off as a mooning, why in the world would he bring it back up and risk that the real truth get out and cause him serious damage? IMHO, no one would do that, hence, why I think his story is more credible and hers is not, especially since her story changed.
Third, if I'm a rich dude with millions in the bank, and something like this happens and I'm advised that I can essentially part with some pocket change to make something go away that's gonna hurt my reputation, I'd very likely part with the cash to make it go away as quickly and painlessly as possible, rather than spend time in court and the national media's headlines.
Finally, in Naughright's original lawsuit, she listed 32 instances of "sexual harassment"....THIRTY-TWO.....including saying that Phil Fulmer had come onto her and that Gus Mannning had "inappropriate communication" with her. Geez, that sounds legit. I casually knew Jamie when I was a student at UT in the late 80s when she lived in Humes and I lived in Reese Hall in presidential courtyard. She was acquaintances with my girlfriend and I actually helped coach an intramural flag football team she played on (before she hurt her knee, tore an ACL iirc). She was a skinny, unattractive Jersey girl....long stringy bleach blonde hair, big ass nose, walked like a dude, just not very attractive at all. A large rack was about all she had going for her. Perhaps that has something to do with all this....perhaps a little insecurity and a thirst for large sums of "easy money" from people and institutions with deep pockets? Probably helps explain her other lawsuit(s) vs Donna Karan as well.
