Sounds like you believe in failing up.
Here's a coach who has been mediocre coaching his position, has had serious personality conflicts with other staff members, has failed in 2 attempts at being an Offensive Coordinator, and publicly copped an attitude with the AD and fans with threats in order to lobby for the HC job when Tucker left.
Your solution, since he had some success as a recruiter when focused on the task, is that CU should have made him the Head Coach.
No way in hell. He's lucky that RG didn't send him packing. He should have. In fact, I'm convinced that RG did not want to lose Chev, knows that he's not capable of being the HC, and the main reason for the KD hire was to assuage Chev by bringing in his old position coach and mentor who Chev would be willing to stay & work for if he got a promotion to sole OC.
