Vujacic knows how to finish (practice)

The exclamations of shock reverberated off the wall of the basketball court at the Lakers’ El Segundo training facility Wednesday afternoon.

Kobe Bryant was laughing so hard, he fell to the floor.

Coach Phil Jackson immediately ended practice.

And what was the source of all this excitement and merriment?

It was 6-foot-7 guard Sasha Vujacic driving down the lane and dunking over 6-10 Lamar Odom and 7-foot Andrew Bynum.

Vujacic, trying to appear nonchalant in the face of the uproar, shrugged his shoulders as he trotted off and said simply, “Two points.”

Odom was more animated.

“He got both of us,” Odom said. “I’ll admit it. I was surprised. It happens. I’ll get him the next practice.”

Said Bryant, “It was the most surprising dunk I’ve ever seen.”

Because of how he did it?

“Because of who did it.”

Behind all the good-natured kidding is a serious point. The Lakers are pleased that Vujacic’s scoring average this season (4.6 points in 12.3 minutes) is up slightly from his average in his first two seasons (3.6). His shooting percentage (41%) has also improved from his previous career mark (32.9%). But Vujacic has been told he could improve even more if he was more aggressive.

“We’ve been on him since he’s been here to go to the basket hard,” Bryant said. “It’s just part of his maturation process to [learn] how hard he has to go to the hole. I have to remind him, ‘Sasha, you are taller than I am.’ It was good to see him go in there and challenge like that.”

So is Bryant expecting at least one such dunk every game now from Vujacic?

“I wouldn’t go that far,” he said.

Odom, out since Dec. 12 because of a sprained right knee ligament, declared himself ready after Wednesday’s practice to return Friday night against the Charlotte Bobcats at Staples Center.

The outlook is not so bright for center Kwame Brown, out since severely spraining his right ankle on New Year’s Eve. He again sat out practice Wednesday.

Hall of Famer Kareem Abdul-Jabbar, who serves as personal coach to Bynum, handed out copies of his new book to the players and other members of the organization after practice Wednesday. It is entitled “On the Shoulders of Giants, My Journey Through the Harlem Renaissance.”
