What planet are you living on? Assume he has no teaching experience then it's $40K to start. Coaching maybe $7K. The guy is a D1 coach.
My school hired the football coach, and offered him a job as a teacher at the same time. He started at the top of the pay scale. Same thing at Longmeadow. It happens often.
Does "started at the top of the pay scale" = $92,000???
If not, it's a pay cut (which is fine, due to the aforementioned reasons in this thread). If yes, then your former school pays teachers better than UConn professors. My guess is that he is taking a large pay cut, but that he is fine with it...
Top of the pay scale is in the 70's in Mass. It's higher in Connecticut. Add $10k for coaching, and he'll do fine in a job with less stress and more job security. Assuming he was hired for more than just coaching.
That is a chicken way to go through life. For his sake, I hope that isn't his reasoning.
