He was the director of operations at Pitt when he first went there, which means he wasn't allowed to recruit, coach or be out on the road representing Pitt. He maybe had some behind the scenes influence talking up an AAU coach or something, but not many recruits go anywhere because they heard great things about the guy booking the hotel rooms and ordering meals. It's a reach to give him credit for Krauser, and yet it's been a common misperception since he did recruit several of the NYC guys who followed. And then there are some people give him credit for the Karl Anthony-Towns class which was recruited before he was hired.
I just watched what he did at Manhattan, which everyone else has always used as a springboard to bigger jobs and wonder why people think he's the greatest thing since bread cut into individual sections of an appropriate size for sandwiches. He did a good job at Pitt, but certainly nothing that should make him sort of legend.
