Homer pick, but Gary Williams. As far as I know, the 2002 MD NCAA champs are the last team without a McD's AA on it. To the consternation of many Maryland fans for many years, he wouldn't dip his toe into the AAU waters - meaning he wasn't recruiting the top kids. On top of that, Gary was never the most.....well, Coaches Cal & K in your living room vs Williams........
I think I saw a stat at one point late in his run that he had more wins against #1 teams (or, #5s or whatever) than any active coach.
