Playing in a major tounament like Eurobasket should give you a lot of experience just check Calderon
and Navarro, its different thing if HE didnt gain it. Thats his fault, not playing in the eurobasket. His one on one defense has improved a lot, but he really needs to start posting more and get some esay points, instead of those imposible three pointers that he does. First make the easy things then the difficult ones.
