IMHO, Here's my rankings as far as overall including men AND women's :
Then there's a tie:
2a. Coach K
2b Coach Auriemma
The task to rate coaches with Women's bball is kind of hard because there's so little competition at the top as compared to the level at men's college ball.
In women's college b-ball, he's the top coach, IMHO.
However, Pat Summitt of Tenn did it the longest and has the most wins. There can be strong debate as far as the women's side of b-ball whether or not she was tops...but in head-to-head, Geno, I think, he has the edge.
