Along with a 6th man, we need another go-to offensive player, as good as Kevin Martin, he just doesn't create for other players, while gets shell-shocked in the 4th quarter.
Morey could easily find a 6th man type scorer in the draft next year with the picks we're getting. No need to trade for one.
By sixth man, I think "game-changer." Right now, the OP is right, no one fits that role. I'm interested to see what Morris can do, because maybe he can be that, but we don't know. I would take a flyer on Smith too, but why? I'd rather have Lee on the court than him, because Lee plays defense. Hindsight is 20/20, but Lin seems like he would have been ideal. He's like Dragic, except he knows how to get teammates involved and he at least tries on defense.
