That's why I'd pass on Swinney. I think he's got lightning in a bottle - the hokey, aww shucks Jesus guy in rural South Carolina. I think that's a persona that reeeeally works if you're winning and reeeeally doesn't if you're not.
He's like a young Bobby Bowden - just missing the grandfatherlyness bit. As long as he has great coordinators, he'll be fine. But if/when FSU, Miami, VT, etc rise back up, we'll see.
But if Dabo Swinney was Michigan's HC tomorrow, I don't think his schtick would fly.
