I am sure he has something planned. Maybe he takes a breather for a year. Maybe he does some analyst work or maybe he has some beer drinking buddies he wants to fish and/or play golf with. Maybe some grand children to fawn over? All of these are noble endeavors.
Jay is a tremendous coach and it wouldn't audprise me to learn he is a pretty down to earth guy as well. It also Wouldn't surprise me to see some coaches just say, how much is enough? He can still be close to the game if he wants, but he's made plenty of money, he can also go live the life he wants w/o the stress of worrying about recruiting and Wins/Losses.
I am sure many are envious in his profession.
