Great point, but I'd say Amir and Ed do as well.
Jose certainly falls into the same catergory of 'making people better'.
Jose's actually averaging more assists per game than Deron Williams, while DWill leads the league in Turnovers.
So you're right, Hump does have a good point guard to pass him the ball. But so do Amir and Ed. And I can't tell you how many times I've screamed at the TV for Amir to PLEASE not shoot that 18 footer that he is so very keen to do.
Again, I love Amir, but I don't see him ever averaging a double-double for a full season.
