Is that a real question? I think his current position, and anyone's current position, is valid to a potential job offer. I think it's quite a bit easier to move him from assistant Illinois to GB DC vs, he's a HC at Iowa (or a DC at UW) and we want him to DC. Weird question.
On point 2, I think that's pretty disingenuous. Maybe Leonhard was naiive, he probably was, but I think it was pretty obvious that one reason he turned down GB the first time was that he thought he was being groomed to run the show at UW. Safe to say that when they didn't bring him on after interim duties that he was heartbroken. And I couldn't care less about UW or JL, it's just reality.
