My brother went to Kansas and couldn't stand him when he was coaching the Jayhawks. Claimed he was a cheater who tried to cover it up with a religious "Aw Gee Whiz, Shucks, Dadgummit" facade.
He also blamed him for bringing in incredible talent and not being able to win it all.
His behind the scenes negotiations with UNC in 2000, where it was announced that he was taking the job, then decided to stay at Kansas only worsened the situation. Over the next couple years he got the Athletic Director fired, leading to this statement...
"This is a sad day for college athletics when a basketball coach has the power to hire and fire a university's athletic director...He had the choice to either crush me with his power of influence or let me fly with my visions for a better total program. He chose to crush me."
Then Gosh darn it, two-faced Roy left Kansas.
