For me it screams out Iguodala, and I'd put money on that too. AFAIK, the Sixer's jersey is pretty much the only one with that wide shoulder as shown on the dunker's right shoulder in the pic, at least to me. And if you search some dunk pics of AI, that's exactly how he goes up for a dunk.

Also with TakeTwo's budget that most likely rules out bigger names.

My second guess would be Brandon Roy.
