I like Butch and would welcome him back with open arms...... that being said, let's be honest here, which is more realistic?
1. Likes coaching in Miami soooo much that he takes a job at a Group of 5 school for much less $$$ where he will never coach for a national championship in his late 60's instead of making much more $$$$ at a Power 5 (doesn't even have to be a marquis program) with a chance at coaching a national champion before he retires.
or....
2. His greatest successes came over 15 years ago, had his name sullied by a scandal at UNC, and therefore was out of the coaching game for 7 years (except for time spent as a consultant for a former assistant's NFL team) so he was a commentator on ESPN. Since no one was knocking on his door, he accepts a Group of 5 job for low $$$ so he can get a few years worth of coaching (his love in life).
Sorry, it's not #1.
