Vonleh is a PF, a tall one that might some day have to flow over to the center position as the skills, if he ends up developing NBA skills, declines, but he is a PF.
I actually think the center position is pretty thin in this draft. Embiid is awfully raw and as a whole is probably behind Anthony Davis and Nerlens Noel, the two big men drafted high in the last two drafts, in his development coming out of college, especially defensively. The back is also a major concern. Look what a concern on Noel's knee did for his draft stock last year.
With WCS and Harrel staying in school that leaves Capela and Nurkic as the only other center prospects worthy of a first round look and both are young internationals, probably the most volatile draft prospects you can find in the first round. So many don't come anywhere close to being what their draft hype predictors and indicators project them to become.
That said, if Capela is there at 18 I think Danny has to take a shot at him if he doesn't land Embiid higher up in the draft.
You know, the best player available at both drafting spots might just be small forwards and Danny might take two of them, not be able to move Green's and Wallace's contracts and have another year where he has a massive log jam at a position. Next year's team could consist of one center, 5 PFs, 4 SFs, and 5 undersize guards that can't shoot. Can anyone say 20 wins?
