First, let's be clear, it is not "his money" just because he had a contract. For it to be "his money," he had to properly perform his contract (and all of its terms and conditions). We are told he was dismissed for breaching his contract by causing or allowing multiple serious NCAA infractions, a violation of his contract. If that is true, it's not "his money." If UT just made up the reason for his dismissal, he may have a good lawsuit. From public information, UT and the NCAA don't appear to think that is the case and, given UT's behavior to date, they seem pretty sure of themselves. UT appears to have fired him for cause based on something they know he did and his lawsuit will reveal exactly what that cause was. No violations, he will win. Violations, thanks for playing Mr. Pruitt.
Second, given that people at UT probably know his attitude and intellectual abilities much better than the average fan, I think it is extremely likely that the administration did, in fact, know these threats would be made and they chose to fight rather than buy him off. The "dirty secrets" of the football program are, most likely, already fully known to the administration and the NCAA. I don't see how he gets any real leverage there. As for other sports, assuming something is "dirty" in them, who in their right mind would have shared the alleged other "dirty secrets" with this guy? What about him would inspire trust from other coaches, like Rick Barnes, with any information that could put those other coaches in jeopardy of ending up where he did for running a "dirty" program? If they trusted him, or anyone else, with any "dirty secrets," I would be stunned. Legal evidence requires personal knowledge. Do you truly think he has any or does this look like a classic litigation bluff?
Finally, I'm not saying nothing else is wrong in the UTAD. A clean as a whistle program would be surprising given today's climate in college sports. What I am saying is, to me, it is unlikely that this guy would have evidence (personal knowledge) of any wrongdoings by others and it is even more unlikely that the alleged misdeeds of others would ultimately have any legal relevance to his breach of contract suit. From everything we have heard, he got caught with a program full of NCAA violations. IF so, he breached his contract. His claim, to me, doesn't get any better if some other guy or girl at UT breached their contractual duty, too.
Based on what we know to date from the public record, I truly hopes UT stands its ground and gives him what he appears entitled to --- nothing.
