if you wanted to draft green im pretty much guessing you're not a fan of Ariza who himself has the potential to become a star in this league at the same position at green..regardless if green becomes a star doesn't mean he would become a star on/for the knicks.
I don't think we needed Green either. I think Ariza has more potential to become a great defender than gerald green does. Green will probably be the better scorer, but Ariza will score, defend, rebound, pass, and hustle. He's going to be an all-around player who can get it done many different ways.
