He’s the kind of guy that runs “to” things, not away from them. If you listen to what he says in interviews, when he leaves to go the NFL it will be:
-To a good situation. The man wants to maximize his potential and those around him. He will not be going to a dumpster fire. He acknowledges the credit he gets as a head coach and shares that credit with everyone in the program, he is self aware enough to know he can’t make a losing franchise a winner by himself.
-To a place he has good relationships. This comes up all the time re: decisions to go to OSU, Cinci, ND. It won’t be to the first place that opens up just because.
Idk if that narrows down the list of possible jobs at all, but coaching in the league and winning a SB is the pinnacle of the sport. He will try someday. Even if he fails, he isn’t the kind of guy to stick around for decades and sit on the laurels of 10 win seasons.
