I'll make an All-Potential Team, for guys who've only scratched the surface of what they could be capable of:
C - Andrew Bynum
F - Dwight Howard
F - Mickael Pietrus
G - Shaun Livingston
G - Andre Iguodala
and for kicks, the All-Potential (in a bad way) Team. The guys who fans/coaches/gms have been waiting on and who haven't or never will take it to the next level:
C - Michael Olowokandi
F - Kwame Brown
F - Darius Miles
G - Kareem Rush
G - Zoran Plananic
