I think there are a few things that need to be separated out. K has won like no one this side of Wooden. K has also had talent like no one this side of Wooden (he’s had more Naismith winners than Kansas, UNC, and Kentucky combined). There is also clear demarcations in his career. No one has been to more FF’s than him, but he is only tied for 4th most this century. He’s won 3 tournaments this century, but arguably his loss to a 15-seed wasn’t his worst first round loss. He’s taken 4 teams with multiple All-Americans to S16 or earlier losses.
It’s one of those Tale of Two cities things. No one wins like him, yet no HOFer loses like him either. We have ESPN to tell us of the former, it’s up to the righteous to fill in the latter.
