I'm not saying I want to see these people coach at UK, nor would they necessarily ever be hired to do so, Im just offering a possible answer to the question of names of competent NCAAT coaches... How about Kevin Ollie who out coached Cal to win the title in 2014? How about Slick Rick who won the NC in 2013 while Cal was being out coached and pummeled in front of 3000 spectators in the first round of the NIT? How about Jim Calhoun who out coached Cal in the FF in 2011? how about Bob Huggins who out coached Cal to make it to the FF in 2010? All of which except Huggins has exactly the same number of NCAA titles as Cal during the same period. Of particular note is Pitino who went to 3 FF out of 6 years with 1 title while at UK with mostly scrub players (Cal is 4 FF out of 6 years with 1 title with mostly elite NBA players). Hell even the Tubster has the exact same amount of titles at UK as Cal. Once again, just answering the question of who else is possibly capable of doing better than Cal, FF and title wise, and most have actually demonstrated it by dealing an exit to Cal's teams in the NCAAT (except ironically Sixteeno).
Here's the problem.
You can always say this, unless Cal literally goes undefeated most years at UK.
He almost always has a talent advantage here at UK, so unless he beats everyone in his path, some people will hold it against him, which is absurd.
The last time he had a significant talent deficit in the tourney, he came out on top against two HOF coaches ('11 vs Matta and Roy).
The last time he reaally had a chance to "prove himself" without a talent edge (at UMASS) when he ran a program that was constantly at a significant talent deficit, he produced a mid major run that was better than Gregg Marshall or Shaka Kahn's, and he only had one player that even had high major offers on the roster.
At the end of the day, you're talking about one game scenarios (basically all losses to HOF coaches with the same or higher seeds - and the Calhoun UCONN team is a bad example - go look at his roster in '11 and tell me there was a talent gap. IF there was one, it was in UCONN's favor).
You're weighing those individual game scenarios more heavily than the entire rest of his body of work, which is insane, because a. he's had at worst the second best body of work at that time and b. because it's a one game format.
If you think that the coach with the best talent 4 out of 6 years should therefore win the title 3 or 4 times or he's underperforming, you're insane. You're not taking into account the other HOF coaches, and the other A+ recruiters, and most importantly,
the statistical reality of a 6 game, single elimination format. And 2 of those years the 3 best players on the team were freshmen.
The single game format thing can not be emphasized enough. All it takes is one bad night. Even the GD '96 Bulls lost 3 games in the post season. That's why in every single pro league (without game time restrictions like in college), they have a series format between teams.
I wish everyone posting on this forum could go back through history and look at typical rates of winning championships for every legendary coach in the modern era. And then I wish they'd all take a course in statistics. Some of this stuff is like persuading someone that the earth is round.
