i agree with nique...but listen
Right now i would say there are four backups better than Lue, those players being Bobby Jackson, a healthy troy Hudson,Earl Watson, and Jameer Nelson.
Then youve got guys like delonte west, eric snow, carlos arroyo, anthony johnson, smush parker, speedy claxton, the immortal rick brunson, milt palacio....Lue is a better player than these dudes
