In extending the league's longest winning streak this season, the Mavericks (39-10) moved within one victory of tying the franchise record. The win moved Dallas one-half game ahead of idle San Antonio for first place in the Southwest Division and Western Conference.

"We don't want to get carried away," Nowitzki said. "Winning 13 in a row doesn't mean anything if you fall short in the playoffs again like we did last year. I thought we were all disappointed for what we did in the playoffs. Ultimately, that pushed us to work harder in the offseason and come together as a team."

The Mavericks won their ninth straight home contest, raising their record here to 20-4. They opened the the 2002-2003 campaign with a franchise-best 14 victories.

"Obviously, we won 14 games in a row that one year and we went to the Western Conference finals, but that didn't mean anything," Nowitzki said. "We still don't have rings. Obviously, its still early and ultimately, we're working on being the best team we can be in the playoffs. I think we're looking good but we still have a long way to go."

Beginning the second half with a 51-38 lead, Dallas extended the margin as Terry scored 11 of the team's first 17 points of the third quarter - including three 3-pointers - for a 68-45 edge.

"Just good ball movement," Terry said. "Guys were breaking people down off penetrations. They made the extra pass. I was open and I knocked them down."

Averaging 23.5 points during the streak, Nowitzki scored 11 consecutive points for the Mavericks midway through the period and added a 3-pointer with 1:12 to go to give Dallas an 80-65 lead.

Before the game, Nowitzki was selected to the Western Conference's All-Star team for the fifth time in his career. He will play for coach Avery Johnson and his Dallas staff in Houston on February 19.

"Its always an honor. ... especially in the West where there are so many great forwards, so many great players," Nowitzki said. "It's tough to get in so obviously, I'm very excited. It should be great with Avery and the coaches there. It makes it special in his first year and with the job he's been doing."

Dallas continued to pour it on in the fourth quarter as Keith Van Horn hit a 3-pointer and Marquis Daniels and D.J. Mbenga made two baskets apiece during an 11-3 burst for a 108-74 advantage with 1:08 left.

"We have tremendous talent coming of that bench," Terry said. "Guys have accepted their roles and they're just coming out and playing aggressive."

"This was a solid performance by the Mavs," Johnson said. "We came out and tried to make it as difficult as possible on them, tried to get back in transition. We wanted to be aggressive on the offensive end and tried to get as many points in the paint as we could."

Van Horn, Josh Howard and Jerry Stackhouse each scored 14 points for the Mavericks, who made 13-of-17 shots in the third quarter and defeated the Heat for the 10th time in 12 meetings. Dallas scored 33 points off 19 Miami turnovers.

"We're very active on defense right now," Terry said. "We're getting our hands on a lot of balls as you saw tonight. It led to a lot of easy baskets for us tonight."

Shaquille O'Neal scored 23 points and Dwyane Wade added 16 for the Heat (30-20) in their most lopsided loss of the season.

"Anytime you lose a ballgame, its painful," Wade said. "When you get blown out, embarrassed, especially on live television, its terrible. You put your hat on and walk out of here cause nobody's got any reason to hold their head up. We got our (butts) kicked tonight."

"This isn't going to shake our confidence," O'Neal said. "It is just a little old-fashioned Texas beat-down. We have to pick it up, especially against the top teams."
