I didn't see the interview with Kelly on the Finebaum show, so I don't know if Kelly gave any specifics. None are mentioned in the article. Outside of the team chef/training table issue, I don't know what else Kelly might have been butting heads over with Swarbrick.
I suspect there is some (if not a lot of) post hoc rationalization in this. Having LSU throw $100 million his way had a lot more to do with his exit, I believe. There is nothing wrong with Kelly leaving to chase the big contract, but at least he could be a little more honest about it.
