A few weeks ago, I watched Jeremy Lin at the San Francisco Pro Am at Kezar in San Francisco.
Yes. He is full Chinese
Yes. He can really dunk
He stole a ball from a NBA Development league player and dunked the ball. Fans went wild.
Best move: he makes a hard cross over and then nails a floater
History: He played for Palo Alto high and now is a starting guard for Harvard. Read SF Gate article on him
Other standout Chinese American basketball players I have played against are Jeremy Lee and Jason Lee.
