I would assume most coaches read into situations that would cause any program embarrassment and try not to emulate them at their own program.
Here are Claeys last 3 jobs
MN Head Coach: ends in program embarrassment whether it was his fault or not
Wazzu DC: ends in program embarrassment whether it was his fault or not
Va Tech: he retires because he doesn’t want to be an assistant, wants to have total control of a defense
doesn’t sound like a recipe for a great hire for a guy who doesn’t know him. If you can’t see that, on paper, he looks like a potential headache, I don’t know what to tell you.
