The Interview with Dvorak and Kanell sounded like he's quite interested in getting back into college football.
He was pretty clear that he's already scheduled to spend time in the spring with old football assistants prominent in current programs, to study how football is changing operationally due to NIL, Transfer Portal, extended scheduling, etc. and "get a temperature" for "things." All of that is the focus for the next three weeks or so, but he's thinking similarly about Fall camps as well.
It will be interesting to see if he would be willing to take a head coaching job at a "non-contending" program to build it, or take a bit less salary, since he doesn't need it, or (unlikely in my mind) an AD job.
