I don't know much about Maryland coach Gary Williams except that they won the national championship while he was there, and he also stacked up seven Sweet 16s there and at Boston College.
I did not follow his teams while he was coaching and there are aspects of his story that I do not like, but I did like his approach to recruiting. He went almost exclusively after less-heralded players and developing them. Dave Odom, former South Carolina coach, said of him that he "has made a living off of the player who is maybe one or two tools short of the complete package (say, height or leaping ability), but who competes hard and plays with a chip on his shoulder" (think Rashad Jones-Jennings). He refused to associate closely with the local AAU coaches because of their questionable reputations.
