I disagree. I know him personally, and he's...from what I can tell, a stand up guy that the media likes to portray a certain way. Isiah Thomas is among his most ardent defenders, and there are many others. I've heard few that know him describe him negatively.
His coaching credentials are hard to beat; among active coaches, only coach K is even worth comparing, and who was Krzyzewski's mentor?
In a world of tremendous corruption, Knight ran a clean program, and managed to win doing it. Who else has done this? Again, only Coach K comes to mind, and Duke is on a whole different level than every other program over the past 15 years.
Knight's back in the Sweet 16; the win over Gonzaga was a real win over a real team; Gonzaga was a #3 seed with 7 straight NCAA appearances.
