He went to a nearby high school that won the state championship against a heavily favored SoCal team. Obviously his being Asian-American is what makes him stand out, but his talent is legit (he's also played in the SF pro-am league and was in the championship game last summer).
Always thought the guy was a winner, he just has that kind of mentality. That last game matched up against Wall, everything he did was the same that he did while at Harvard. I just never thought he would make an impact quite like he has (and I've NEVER seen any player just rip the ball away like he does from other players' hands).
