Quick help please! Pickup up JR Smith or Tyrus Thomas?

i would get rid of Joe Smith... he barley played tn in his Cav's debut....it doesnt seem like they r going to use him as much as many people believed.......Well i dont no who the best players left on free agents... but if Wally Syrbieack (butcured the name) is there take a chance and pick him up... he met get some good time in with the cav's and he'l be sure to knock down several three's with lebron being triple teamed
