If LeBron James becomes a free agent, he might have second thoughts about joining the salary-cap friendly New Jersey Nets.

These fans booed him when he dunked.

James has double-double as Cavs toy with Nets.

It happened not once but twice in the Cavaliers' 111-92 victory over the Nets on Wednesday night.

Forget that James had 26 points and 14 assists, one shy of his career high. The King disappointed the 17,502 fans at the Izod Center when he gently dunked two first-half fastbreaks instead of putting on a show with a rim-rocking jams.

"I guess that's how much they love you when they boo you," James said after the Cavaliers won their fifth straight game by opening a 20-point first-quarter lead and coasting.

When James did unleash a furious jam later, the fans who made up one of the largest home crowds the worst team in the NBA has drawn this season were back on his side - and no doubt hoping he noticed their appreciation.

The win completed a two-game sweep of the Knicks and Nets over the past three days, the two teams that have a ton of money to throw at James this summer. James put on a show for both.

"From my seat he looked good doing everything," Nets interim coach Kiki Vandeweghe said. "I have seen him enough, seen him on television and a number of times in person and he keeps getting better and better."
