Wooden
K
Calhoun
What Wooden did was amazing. Yes, there was some shadiness but still it was an amazing dynasty
K just edges Calhoun, IMO
Calhoun built a program. Maybe only K could have done what JC did.
Without giving a specific numerical rating for Calhoun, except that he should be in the top 5, another positive metric for him was his postseason record. As I recall, he had a high winning percentage once the team got to the NCAA.
However, and I have not researched this, I think I also once read that his record against top 50 teams for his coaching years, during the regular season was around 500.
Maybe the statisticians out there can verify and quantify my assumptions.
The fact is that he took over a mediocre team to great heights in a highly competitive league, the Big East , with 3 national championships to boot plus his post-season games were always competitive with the team never being blown out in a loss.
