It's 100% accurate. When ND fired Weis, Kelly probably crawls over broken glass from Cincinnati to South Bend to get that job. Then 11 years later, he flies out of South Bend to Baton Rouge like Clark Griswold sledding down the hill.
These are just jobs for these guys. Every last one of them. So when the plan to keep a good assistant coach is just to keep giving him a raise so he'll stay, you're basically an idiot for suggesting it and you're going to be left disappointed. They don't care as much as you do. They're not fans. Mike Mickens, for all intents and purposes, doesn't give a fuck that 20 people on this board want to give him a massive raise so he'll never leave. He has multiple contingency plans for whatever his next move is.
