Oh, I don't know; I think it depends on what you mean by best coach. He won a lot of games, for certain, but he didn't contribute much to basketball in terms of changing the game, and he doesn't have much of a coaching tree. I think it's also fair to raise the Sam Gilbert issues, as it is certainly worth noting that Wooden was at UCLA a long time--never winning anything--until Gilbert showed up.
Greatest "coach," at least in terms of changing the game, has to be Hank Iba. The guy invented the motion offense, which is used by nearly every organized basketball team in world. He perfected man-to-man defense, and has a coaching tree a mile long.
Whatever! Coach Iba preceeded Wooden and all those other greats in his coaching tree. Wooden is listed in that same tree.
But c’mon 10 national championships in 12 years!
That feat will never be equaled and I don’t care what you say about Gilbert, you are simply wrong, wrong, wrong.
Maybe you should start another thread or two - one for each of your role models. /s
