"lottery picks" obscures the fact that Felton, May, and McCants were all NBA busts. Felton never had an NBA season even as efficient as the one Caleb Love is having right now. the NBA, like all leagues, is just better at drafting now than it was 20 years ago, so it's not really a great cross-generational measure of talent.
you may as well look at high school rankings. RSCI had Felton #3, McCants #4, May #9; it also had Love #13, Bacot #23, Davis #43, Puff Johnson #59, Leaky Black #64 (Walker Kessler #18, Dawson Garcia #35, as we remember some guys). Certainly 2005 has the edge, but I maintain that having the latter group taught by Roy is a better base than the former group taught by Doh.
