NEW YORK - After nearly two years of bickering, NBA players and owners are back on the same side.
"We want to play basketball," Commissioner David Stern said.
Come Christmas Day, they should be.
The sides reached a tentative agreement early Saturday to end the 149-day lockout and hope to begin the delayed season with a marquee tripleheader Dec. 25. Most of a season that seemed in jeopardy of being lost entirely will be salvaged if both sides approve the handshake deal.
Barring a change in scheduling, the 2011-12 season will open with the Boston Celtics at New York Knicks, followed by Miami at Dallas in an NBA finals rematch before MVP Derrick Rose and Chicago visiting Kobe Bryant and the Lakers.
Neither side provided many specifics about the deal, and there are still legal hurdles that must be cleared before gymnasiums are open again.
"We thought it was in both of our interest to try to reach a resolution and save the game," union executive director Billy Hunter said.
After a secret meeting earlier this week that got the broken process back on track, the sides met for more than 15 hours Friday, working to save the season. Stern said the agreement was "subject to a variety of approvals and very complex machinations, but we're optimistic that will all come to pass and that the NBA season will begin Dec. 25."
The league plans a 66-game season and aims to open training camps Dec. 9, with free agency opening at the same time. Stern has said it would take about 30 days from an agreement to playing the first game.
"All I feel right now is 'finally,' " Miami Heat star Dwyane Wade told The Associated Press.
Just 12 days after talks broke down and Stern declared the NBA could be headed to a "nuclear winter," he sat next to Hunter to announce the 10-year deal, with either side able to opt out after the sixth year.
"For myself, it's great to be a part of this particular moment in terms of giving our fans what they wanted and wanted to see," said Derek Fisher, the president of the players' association.
A majority on each side is needed to approve the agreement, first reported by CBSSports.com. The NBA needs votes from 15 of 29 owners. (The league owns the New Orleans Hornets.) Stern said the labor committee plans to discuss the agreement later Saturday and expects them to endorse it and recommend to the full board.
The union needs a simple majority of its 430-plus members. That process is a bit more complicated after the players dissolved the union Nov. 14. Now, they must drop their antitrust lawsuit in Minnesota and reform the union before voting on the deal.
Because the union disbanded, a new collective bargaining agreement can only be completed once the union has reformed. Drug testing and other issues still must be negotiated between the players and the league, which also must dismiss its lawsuit filed in New York.
"We're very pleased we've come this far," Stern said. "There's still a lot of work to be done."
The sides will quickly return to work later Saturday, speaking with attorneys and their own committees to keep the process moving.
When the NBA returns, owners hope to find the type of parity that exists in the NFL, where the small-market Green Bay Packers are the current champions. The NBA has been dominated in recent years by the biggest spenders, with Boston, Los Angeles and Dallas winning the last four titles.
"I think it will largely prevent the high-spending teams from competing in the free-agent market the way they've been able to in the past. It's not the system we sought out to get in terms of a harder cap, but the luxury tax is harsher than it was. We hope it's effective," deputy commissioner Adam Silver said.
"We feel ultimately it will give fans in every community hope that their team can compete for championships."
The league hopes fans come right back, despite their anger over a work stoppage that followed such a successful season. But owners wanted more of the league's $4 billion in annual revenues after players were guaranteed 57 percent of basketball-related income in the old deal.
