I've seen all of China's exhibition games this summer in preparation for the olympic. Sun Yue is by far the best defender and shot blocker on team China. The guy just has unbelievable timing on shot blocking especially in transition. Despite that however, i dont see how he can get regular minutes on this crowded Laker team. I think he is going to be a crowd favorite and the designated human victory cigar. He's exciting to watch but he isn't ready to contribute on an NBA championship squad quite yet.
He has 3 HUGE major weaknesses and until he fixes those, he is unlikely to receive any playing time. For one, the guy has no NBA 3 point range. He's a dreadful shooter. Undoubtely the worst shooter on China's national team.
Additionally, he also can't dribble nor finish with his right hand. If you think Lamar Odom's right hand is useless wait until you see Sun Yue.
Lastly, like many other Chinese basketball players, he is extremely passive. Unsefish to the extreme. He's one of those guys that would give up an open layup for a corner 3 to a teammate. He has no ability to score in the NBA whatsoever.
When he learns to shoot and stay confident he'll be a very good player. Give him 2 years.
