Cassell, Pollard and Scal are basketball players. Gerald Green, not so much.
The first time I saw Gerald playing for the C's, I remembered when Kandi was drafted with the 1st pick, then came to Europe to play for Kinder and everybody went: "wow, he doesn't even know how to play...". With Gerald, it was that exact same feeling, as it is with some projected lotto picks in this draft.
Eventually, they'll learn some things, just not enough to make them NBA-caliber players. People are fooling themselves when they believe that Green has potential. He has terrific athleticism, but that's not basketball potential.
