The Spurs have gone to a new low, with assassin Udoka deliberately swinging his leg at Dirk pinning his leg so as to put pressure on the bone. Just look at the video on NBA.com and you can see for yourself. Udoka is coming in for a dunk, Dirk goes up to black the shot.
Instead of continuing forward, like a normal player Udoka spins so that he is now facing downcourt, falling on his back. He swings his left leg, which catches Dirk's as he is landing. Udoka's leg prevents Dirks, from coming out from underneath his body, and he ends up falling on it.
Nobody will believe that this was deliberate, but Udoka had to work very hard to turn around to be in a position to do what he did. A normal player would have run into the stantion and stopped himself on the padding. Udoka spun his body around backwards. WHY would anyone do that deliberately, fall backwards so they couldn't see where they landed?
Scumbags. Udoka should be suspended and the Spurs not allowed to replace him.
