He can claim that all he wants. Fact is, he called his school's student body and his city out for their shitty support just halfway through his first season and immediately started looking at job offers even after he was offered his extension. If he really wanted to stay, he would have accepted it immediately, instead he continued to shop.
My guess is, he overplayed his hand. He thought one great season would parlay him into a premium job and instead the bulk of the interest came from bottom feeders or mid-level P5 teams. So he took the $3M and will try again next season.
BTW, I heard his radio interview from earlier this week. This guy is a psycho and borderline retarded with his understanding of basic conversation.
