That, AND they both got him at his worst. Ma Long is really off his game here, and he had just come back from an injury when he went up against chan kazuhiro, so he was a little bit sluggish.
i think everyone in japan is going for big points by training to beat ma long specifically. seiya beat ma long, and recently, chan kazuhiro beat ma long VERY VERY badly, 3 games to none. i had never seen ma long shut down so badly by a blocker like chan kazuhiro.
