Juwan came back with the goal of exponentially improving his perimeter shooting. He improved last year and believes he has a real shot at the NBA with further improvement. He knows his future is at the 2/3 rather than at the 4. So yes, he will certainly see minutes at the 4, but I think he really liked being slotted at the 3, like he was this past year.
Given the tenuous situation with Rienk, I would love the addition of both Kyle and Igor.
