Blue = Good pick/value in the draft
Red = Horrible pick
I would say that he can find value in the lower rounds but when he misses, he misses big. Cleaves, Rodney White,and Darko were horrible considering the below players he could have had instead :
Bosh/Wade/Melo in '03 , Joe Johnson, Tony Parker, Richard Jefferson in '01 and Turkoglu, DeShawn Stevenson, Michael Redd in '00
