Titles dont signify squat. Look at Kevin Ollie, how'd he do after Calhoun gifted him a Ferrari? How'd Tubby do when the Pitino shine wore off?
Coaches should be judged on how often the team was in the position to win a title, like Final Four appearances. Because in the final four, every game is decided by a few free throws or a made/missed 3 with 20 seconds left. Was it Caliparis fault that Liggins missed that 3 against UConn? Was it Pitinos fault they didnt kick Laetner out of the game after the stomp? Titles require a great team with some great luck. As billy donovan used to say, "only half the time does the best team actually win the tourney. And if you replayed it a week later, you'd get an entirely different field."
That said, the best UK coaches...
