LOS ANGELES -- LeBron James and Kobe Bryant ran their mouths while they jogged downcourt, not quite making eye contact during an unpleasant conversation in the closing minutes.

"Just asked him what he got for Christmas," James said.

Although the two superstars wouldn't reveal what angry words they exchanged, it wasn't tough to pick out a few statements Saturday. While Kobe and the Los Angeles Lakers got a disturbing first look at the Miami Heat, LeBron got the last word at Staples Center yet again.

James had 27 points, 11 rebounds and 10 assists while hitting a season-high five 3-pointers, and the Heat thrived on the holiday stage in a 96-80 victory.

Although both teams called the game a television curiosity rather than a potential NBA Finals preview, it clearly meant something to James, who had his third triple-double with Miami and the 31st of his career. James also outplayed Bryant, who scored 17 points, in his second straight Christmas win in the Lakers' home arena, following last season's victory for LeBron's Cavaliers.

"We're not trying to make a statement to anyone," James said. "We're trying to show each other that we can play at a high level and try to get better every game. This is one game. ... We're happy because we got better today."

While the Heat realize Boston and Orlando are much more important obstacles to their championship hopes, and while the Lakers don't get terribly excited about playing anybody until the playoffs, there was a palpable edge in the crowd at Staples Center for this intersectional matchup -- until the Heat's steady defensive effort flattened the Lakers in the second half.

Chris Bosh had 24 points and 13 rebounds, Dwyane Wade added 18 points on a sore knee and the Heat won for the 14th time in 15 games while flustering the two-time defending champions into a terrible offensive performance, starting with Los Angeles' 14-point first quarter.

"Our whole thing is just playing solid defense the whole game," Bosh said. "That's the primary part of our identity. Our backbone right now is defense."

James played a balanced, patient game, even after a technical foul near halftime for an under-the-basket scuffle with Lakers defensive stopper Ron Artest. James' teammates contributed enough to keep the Heat comfortably ahead, with Bosh playing an outstanding first half and Mario Chalmers contributing 13 points in a reserve role, including three 3-pointers.
