Hard to say.. McCallum didn't try to run the offense at all, and got picked twice. I will say this - if the plan is to throw PG#2, Thornton, Williams, Outlaw, Gray or basically a lineup that doesn't have either Gay/Cousins/JT in it, then the better option is to go for McCallum, who has a more confident handle and will probably look to drive and dish more. I actually think Jimmer would probably be at his best in a starting role playing off of Cousins and Gay, because he plays good team ball and will stay out of their way while helping to space the floor together with McLemore. This allows IT to come off the bench with Williams against the opposing bench, and we shouldn't lose any momentum at all. Best balance this way IMO.
