Greg Smith was an undrafted player who was signed from the D-League. Even though he was recently sent down to the D-League to work on his game (mainly to improve his defense, but McHale was quoted as saying Smith lost his energy and stopped doing things like using both hands to try and pull down rebounds) and replaced in the rotation by Cole Aldrich, my point isn't that he really sucks but that similar talent may be freely available. Henry Sims seems to be talked about as a guy with upside among D-League watchers.
