EAST RUTHERFORD, N.J. — With free agency awaiting him in 2010, LeBron James put on a show for the New York metropolitan area and its deep-pocket teams highlighted by a length-of-the-court sprint to block a dunk by Devin Harris.

James had 31 points, eight rebounds and four assists in another dominating performance and the Cleveland Cavaliers rolled to their eighth straight win with a 106-82 decision over the New Jersey Nets last night.

The play that everyone will remember is the block. The 23-year-old James came from 20 feet behind to track down the Nets point guard, forcing him to rush a dunk that the high-flying James touched.

"I just never gave up on the play," James said. "That's how we all are. You never give up on plays no matter if a guy is in front of you or what."

Harris laughed when asked if he saw James coming at full throttle.

"He's 6-9 and 260," Harris said. "You try to quick dunk him if you can. If not, hey, he got a piece of it. He came back and he played it. If I had a good ankle, now that would be something to think about. You got to go for it. I had my shot at it and I missed it, you move on."

The question of moving on is a big part of James' life. He is scheduled to become a free agent in 2010, and there already has been speculation that the Nets and the New York Knicks are already clearing salary cap room to make a run at the superstar who last night became the youngest NBA player to reach the 11,000-point plateau.

Before the game, James said he would not hesitate to leave Cleveland if another franchise offers him a better chance to win multiple NBA titles.

"I think you do what is best for you and you do what is best for your career," James said when asked about his sense of loyalty to the Cavaliers.

James (23 years, 323 days) replaced Kobe Bryant as the youngest player to score 11,000 points when he hit a jump shot late in the first quarter. Bryant of the Los Angeles Lakers was 25 years, 99 days when he got 11,000.
