And you do so who's better?
I never said I had a definitive list or ranking, but I'd start with Izzo, Self, Wright, K, Beilein, and maybe Bennett, Huggins, Marshall, etc.
Is this really that controversial? In 2012, Roy was asked in the postgame about KU using a triangle and 2, and his response was "I know they did for one possession, maybe two." They used it for 10 min.
Roy has areas that he excels in, but situational coaching and drawing up plays out of timeouts, etc is not his specialty.
