Looking at it differently, a guard is supposed to make shots, create opportunities for teammates, and spread defenses. That's why he's on the floor, no?
By failing to do these things, one could say that he commits plenty of mistakes.
Whatever, Sprads is who he is. Other than maybe Martavious, we don't really have any other options. Let's just hope that he'll come out against Cuse and shoot 40% from behind the arc, play decent defense and have 3/1 A/TO ratio.
