I think Dioubate will play mostly PF, but also some spot SF. We could have four different solid players on the floor at any given time at the 4: Williams, 6'8; Garrison, 6'10; Dioubate, 6'7; and if we get him, Alvaro at 6'9.
I think DO and Alvaro could absolutely coexist. I see us having three guys who can play C next year between Alvaro (small ball), Garrison, and Moreno, so there should be plenty of minutes to go around down low.
Pope is building a monster team next year.
We knew Chandler and Oweh were athletic, but Kam, Dioubate, and the freshmen guards all collectively upgrade the athleticism from last year's team. No knock on them, of course.
Add in Pierre or someone like that and again, Pope well have a monster roster. I feel like we'll have a lot more open looks from three next year.
