One name I have not seen thrown around is Ante Tomic.
He is a 7' 2" center, plays for Barcelona in Euroleague, received multiple awards there and has solid stats.
Check out his profile at Wikipedia:
If you are interested you can check him out on YouTube, but in his case stats tell the whole story.
The only problem is that his draft rights are held by Utah Jazz, which means we can not sign him right away.
However, Jazz might be willing to part with his rights for minimal compensation - after all they have Favors and Kanter.
So, Philly pick will probably get the deal done, however it might be too steep of a price.
In any case, this post is for your information, because I have not seen his name thrown around as a possibility at all.
