Numbers of note: Mavs nearing finish line

Some Mavs numbers of note this week entering the final five games of the regular season:

12: If the Mavericks can’t buck the overwhelming odds against them to sneak into the playoffs and extend their run of 12 consecutive trips to the postseason, Denver will supplant Dallas as the No. 2 team on that list with a streak of 10 consecutive playoff seasons. The Nuggets, of course, visit American Airlines Center on Friday night. (Southwest Division champion San Antonio will make its 16th straight postseason appearance this spring.)

3: With his old friends from Phoenix in town, Shawn Marion will be trying Wednesday night to reach the 20-point plateau for the third consecutive game, something he hasn’t managed since February 2007. Marion has also posted two 25-and-10 games in his last 19 appearances for the Mavs, after the 34-year-old crafted just two such games in his first 260 regular-season games in Dallas.

0: One of the many areas that cost the Mavericks this season has been their total inability to beat elite teams on the road. They’re 0-12 this season in road games against teams with records of .600 or better.

6: Dirk Nowitzki's six single-digit scoring games in 2012-13 are his most in any one season, not counting his rookie season. Nowitzki has averaged just 11.5 points on 40.9-percent shooting in Dallas’ past four games.

10: The Mavericks’ highest position in ESPN.com’s weekly NBA Power Rankings was No. 10 … but that was way back in the preseason edition of the rankings on Sept. 28. They haven’t been higher than No. 15 since Week 3 of the regular season began Nov. 19.
