Absolutely not, you let him finish his career here if he will (and hopefully he does). He’s recruiting extremely well, he has a great staff, he’s well liked and does things the right way, and he hasn’t suddenly forgotten how to coach.
Every team is different. Sometimes it’s harder to get a certain group to play well together and to push the right buttons with everyone. A similar example IMO would be KY this year. It’s possible they can even get things turned around this week with a week of practice..
