This is why when it is all said and done despite playing in an era of Coach K, Roy Williams, Jim Boeheim, Rick Pitino, John Calipari etc you can make a case that Bill Self will be the most accomplished coach EVER. He probably won't get to 5 NC's like K but his run at Kansas is quite frankly getting to be every bit as good if not better than all of those coaches.
He has been at Kansas now for 20 years and before that Illinois for 3. So 23 years at a high major. He has won or shared conference regular season title (Big 10 and Big 12) in 19 out of those 23 years. The other 4 seasons he finished 2nd 3 times and 3rd once.
It is a ridiculous run of sustained success that is bordering on what K did at Duke, what Roy did at Kansas and UNC and what Rick had going at Kentucky before he left for the Celtics.
