Smith can stretch defenses. He's a better SG than anything they have now.
That starting lineup is looking really interesting now:
Add in Baron Davis (when he finally gets in shape/ healthy), Novak, Fields, Harrison, and Shumpert and you've got some guys who can give you minutes too.
With luck, they just might get to second place in the Atlantic behind Philly and a top four seed in the playoffs. (Which is the real advantage here.)
