Exactly. Phil was a "genius", Jordan could not win one before being coached by him. Same for Kobe.
But Phil's "genius" wasn't the triangle offense - that was brought by Tex Winter, his assistant (well, perfected by Tex, originally devised by HoF Sam Barry) - it was his psychological prowess in getting some super-gifted, super-competitive, super-stubborn athletes transcend their individual abilities and buy into a system.
And Geno is in that regard is the Phil Jackson of WCBB. He is a master of forging diamonds by finding the right buttons to push for each player and maximizing their potential. And I don't mean to diminish the role of recruiting (in which CD played a major role from the beginning), where it all actually started with local talent (Bascom, Lobo) of not quite the caliber of DT, Maya, Stewie, but going all the way to the first FF and the first NC.
One more note about the often-quoted "not so great" record of Geno in the SF. Bringing the team now 17 out of 18 consecutive tournaments to the FF is absurd, irrespective of the talent across these two decades. Many of those SF losses came during this incredible stretch. Why? Because (to Geno's own admission) many of those teams had "no business being in the FF" - i.e. they were overachievers to get that far. He made them overachieve to get farther than they "belonged". The teams that did "belong" in the FF generally won the SF game as well as the NC (some exceptions, of course).
