Hopefully DA won't pick a dud (not necessarily duds but just ppl coach won't play) like he has the past 2 years. There have been numerous awesome picks in the range 20-30 over the past 15 years:
@ 21: Michael Finley, Boris Diaw, Nate, Rondo!
@ 23: Tayshaun Prince, Travis Outlaw
@ 24: Delonte West
@ 25: Al Harrington, Gerald Wallace, TA
@ 26: K-Mart
@ 27: Perk!
@ 28: Tony Parker, Leandro Barbosa
@30: A Varejao
