Just in time for Christmas, here comes the matchup that was on the NBA’s wish list in June.

The Kobe Bryant-LeBron James showdown didn’t pan out last season, but now it arrives in Hollywood with the addition of basketball’s biggest supporting actor: Shaquille O’Neal, formerly Bryant’s teammate, now James’ sidekick.

The Cleveland Cavaliers visit the Los Angeles Lakers on Christmas Day, claiming top billing on a five-game schedule. And while the meeting is loaded with subplots, it also comes with a question.

Could this really be an NBA finals preview?

“Without a doubt. Definitely,” Lakers coach Phil Jackson said. “They’re going to be an elite team. They got off to a slow start, they had some issues with new personnel to blend in and they’re going to start playing well. Too talented a team not to pay attention to.”

But while Jackson’s team leaves no doubt of its championship potential, Cleveland has been ordinary too often, more hype than hope, for some critics. Charles Barkley essentially pronounced the Cavaliers dead two weeks ago on TNT, saying there “are only two dogs in that (Eastern Conference) race. Orlando and Boston are by far the best two teams in the East.”

What about that, LeBron?

“It’s too early,” James said. “Boston, Orlando are playing well. Miami’s played great at times. There are a lot of good teams. We’re happy we’re in the position we are. There’s a long way to go until it all shakes out.”

The season is nearly two months old, but Christmas is traditionally when the NBA makes its first big splash. The league and ESPN are heavily promoting the Cavs-Lakers game, which follows Boston at Orlando on ABC.

New York opens the schedule with its return to Christmas competition by hosting the Heat. The Los Angeles Clippers visit Phoenix later Friday before Northwest Division rivals Denver and Portland meet in the nightcap. It’s the second straight year the NBA has staged five games on Dec. 25, the most it’s scheduled on the holiday.

The Knicks will be decked out in green jerseys for their league-high 45th appearance on the holiday, having played in the first set of Christmas games in 1947. The Trail Blazers will try to improve the NBA’s best Christmas winning percentage, having gone 13-2 thus far.

Still, the most attention goes to the biggest names, and that’s Bryant, James and O’Neal.

The defending champion Lakers returned from a five-game road trip with a 22-4 record, looking like a heavy favorite to get back to the finals for the third straight season. Even with Bryant nursing a broken finger, they appear even stronger than the team that overwhelmed Orlando in five games in June.

Cleveland improved to 21-8 by handing Phoenix its first home loss with a 109-91 rout Monday, a dominant performance on both ends of the floor that was a reminder of how good the Cavs can be.

“Contrary to what anybody may think, to get to the Eastern Conference championships, you are going to have to go through Cleveland at some point,” Suns coach Alvin Gentry said.

Yet the Cavs were only good enough for fourth place in the East behind Boston, Orlando and Atlanta after that win, with their mediocre road play, occasional offensive droughts and lack of productivity from O’Neal reason enough to question them.
