I think it has more to do with him being 230lbs instead of lack of athleticism....I mean he's not Fox or Wall speed-wise but he had no trouble dunking it either....if he sheds some poundage like you said, he'll probably be quicker and more athleticHe definitley does lack athleticism that we are used to. His handles are suspect and doesnt appear to be in bball shape, both of which can be attributed to focusing on baseball for the past several years.
He can definitley add strength while getting leaner and has a sweet shot with range, probably has a more old school game than flash and sizzle, which is ok with me.
