In your opinion, based on facts, are there any other not good coaches that have built mid-major programs into Sweet 16 teams?
Yeah. Cuonzo Martin. Who got to a S16 at our school. KO made exactly one sweet 16 in his entire career. I have better things to do with my time than look up every coach who ever made a sweet 16, but my guess is there's an enormous amount of forgettable names on that list.
If you keep getting fired or bouncing to lateral or lesser programs, it's a pretty good indicator of your coaching status.
If you want to stand on a pillar and shout the successes of a guy who was a pretty consistent loser, then... ok that's cool I guess. He's lost a lot more than he won overall. He's lost a lot more in individual seasons than he's won. I'm not sure what more you need to say about it. If he were a good coach then I would expect more good coaching.
