You know, if you put a "sniper" on Joey's wing, it could mess up his whole game. He might start trying to pass and set up the sniper rather than being his own "sniper". Chemistry can be a funny thing. Right now it is working with Joey and Nick and RJ. Perhaps the old "if it ain't broke, don't fix it" cliche should apply here.
Are you suggesting perhaps he only needs a better set-up man than Umby?
