#5 is weird, he has no right to have a chip on his shoulder, he wasn't fired by the U, he left because he couldn't handle it health wise. The U bent over backwards for him while he dealt with the health issues.
Probably refers to the time between when he left the U and now. My guess is that he has been actively trying to get back to being a head coach this whole time because he just can't handle not being the guy in charge of the football team. And teams probably weren't willing to hire him for that role because you know....he left the U since his health couldn't handle it.
