For different reasons, the Dallas Mavericks and Seattle SuperSonics each have not played a meaningful game in at least a week.

The teams conclude their vastly different regular seasons Wednesday when they meet at KeyArena.

Dallas (66-15) has been resting starters and key players since clinching the NBA's best record and home-court advantage throughout the playoffs. That trend continued Tuesday as Dirk Nowitzki, Jerry Stackhouse, Josh Howard and Erick Dampier all did not play in Tuesday's 111-82 loss to the Golden State Warriors, who completed a sweep of the Mavericks and may be their first-round playoff opponent in the Western Conference.

You've got to play somebody," Mavericks owner Mark Cuban said. "The Warriors are a good team, and that's Nellie's style of ball... It's not about Nellie, and it's not about the Warriors. It's about how we play."

A win would put the Mavericks in elite company with the sixth-best single-season record in NBA history, joining the 1985-86 Boston Celtics, 1991-92 Chicago Bulls and 1999-2000 Los Angeles Lakers -- all squads that finished 67-15 and would eventually win NBA titles.

Mavericks coach Avery Johnson had a makeshift lineup on Tuesday that included Greg Buckner, Devean George, DeSagana Diop, rookie Maurice Ager and Jose Juan Barea -- five players with a combined 33 starts this season. Ager scored a season-high 20 points while Barea added 13 and 10 rebounds in his first NBA start.

Regardless of who plays for the Mavericks, they will be trying to complete a second straight season series sweep and win their 10th consecutive game over the SuperSonics (31-50) since a 107-102 loss Dec. 9, 2004.

Seattle, which will miss the playoffs for the fourth time in five seasons, has lost four straight and eight of its last nine following a 109-98 loss to the Los Angeles Lakers. The Sonics -- who never led and allowed Kobe Bryant to score 50 points -- need a win to avoid their worst finish since going 26-56 in the 1972-73 season, a task that will be more difficult without injured starters Ray Allen, Luke Ridnour and Earl Watson.

"I thought we played great," Seattle coach Bob Hill said, "and we didn't have anybody."

Rashard Lewis scored 24 points, Mike Wilks added a career-high 22 and Chris Wilcox had 20 and 10 rebounds for his 20th double-double.

The game might also be the last for the Sonics in Seattle, the franchise's only home since joining the league in 1967. The Washington state Legislature announced Monday it will not vote on a bill that would have provided funding for the proposed King County Events Center in a legislative session that expires on Sunday.

Sonics owner Clay Bennett has said the team would only be viable in Seattle with a new arena.

"Clearly at this time, the Sonics and (WNBA's) Storm have little hope of remaining in the Puget Sound region," Bennett said in a statement. "By its inaction, the Legislature has delivered the message that they are indifferent to the notion of the Sonics and Storm leaving the market."

Reserve Austin Croshere had career highs of seven 3-pointers and 34 points off the bench to lead the Mavericks to a 122-102 win over the Sonics on Jan. 30.
