The key for any hope of an NBA career for Erden is if he can rebound and play some defense. It would be nice to see him against Scola, Varejao or Krstic in the WC. That would end or clarify a lot of this speculation we all have.
The reality is, we will not know what kind of NBA game potential he has until we see him in camp against KG and JO. Then hopefully in a preseason game or two. If he is moderately athletic when in shape and not afraid to bang down low, he has a good chance to make the roster.
I think we will see him work with Clifford Ray a lot if he makes the roster. The D league would be a part of his future as well. I am surprised we havent heard any news about him working with anyone yet.
It is really still too early to make anything but an uninformed prediction.
