I know the guy is small and may have some baagage, but the guy is an unrestricted free agent and in 06-07(his last yr w/ actual playing time) he avg nearly 5ast and 15ppg.
If we do not make any other moves or can not get Marbury/Brown, who ever. I would think this guy is worth a look if he is in shape and ready to play.
Though I did just read a Wikipedia page that said he is playing in an Italian league but was cut for behavioral issues then was let back on the team?
