Personally, my only gripe with how selfie concluded his tenure at Illinois
Totally get why people have strong feelings about it. Some insiders posted long after that Guenther thought he had a deal, and wouldn't keep playing ball when the bidding went up. No idea how much, if any of that story is true, but in retrospect, a coach doing what's in his best interest seems pretty normal. If you didn't like some of Self's personality, though, that ending would seal the deal. For me, it doesn't make a lot of sense to love his salesmanship when he was recruiting and running the program, but then turn around and hate him for being a salesman in many other respects, like shopping around for the best salary or AD or booster support.
As far as the NCAA's pathetic handling of the FBI investigation into player payments, I put that on the NCAA. It's mystifying how willfully uneven the rules enforcement is, but that's another story.
