I've also seen us linked to Willie Cauley Stein. He'd be interesting, better athlete than Fab and even Kentucky role players have been finding success in the NBA like Patrick Patterson and Eric Bledsoe.
He can jump, block shots, shoot at a high percentage and maybe even run the floor. He might just stay to win a title next year with the Harrisons though.
My dark horse pick would be Alex Poythress. I think we'll draft by best player available as opposed to someone like Olynyk. With his athleticism he's more of a sure thing at the next level which would make him a good trade chip like Moe Harkless was for Philly.
