I would be interested to see him go back to coaching college, with how different it is now from when he coached there last. All the spread offenses, managing NIL, etc. Be curious to see if he could take over a smallish program and build it up.
I can't see him coaching in college with all the recruiting commitments at his age. That's especially so with the transfer portal and NIL. I can't see BB wanting to deal with that and having to deal with the issues of 18 - 22 year old kids.
