I would say so far that none have. It's not just that he has won 11 NC's and nobody else is even close (except for the great Pat Summitt). It's the history of sustained excellence. For that history, Summit comes close - she won 6 NC's between 1987-1998 then had a gap (some NC finals losing to UCONN), then won a pair in Parker's years (would NOT have happened without the JUCO transfer Bobbitt IMHO) 2007-2008. That's a 20 year span to win 8 NC's. So incredible.
Having said that, since Geno's 1st NC in 1995, he's won 11 thru 2017. Sadly, with Pat no longer with us, there is no other coach that even comes close to the success Geno has had. And it's not that he's selfish with his desire to share. He has invited pretty much anyone who wants desires, to come watch practices and see how he does it. Cori Close and several others have taken him up on it.
For all the ribbing that UCONN fans gave Pat for going to Harry for advice on offense (there were funny photo shopped pictures of them in a hot tub), you absolutely have to give Pat credit for knowing what she didn't know, and going out to try to fix it. Geno has done the same thing - famously going to NBA games and picking the brains of some of the greatest coaches in the league. He's a sponge and a true student of the game - never ashamed to ask and learn something new. He has an ego, but not where learning is concerned.
It's not just about fitness and intensity tho. There are many clips of Geno at practices. I know he doesn't run every single practice for 2 hours from start to finish, but when he's out on the court with the players, he's CONTINUALLY coaching, talking, teaching, yelling, instructing, etc etc. I can't see how any kid could go to a practice and not be blown away at his coaching brilliance. It's something that IMHO no other coach possesses, not even Tara or Muffet (IMHO the 2 best other coaches not named Geno).
