Big D? Just call it Alley-Oop, USA

Alley-oop capital of the United States?

These days it has to be snowy Dallas, Texas.

What other conclusion can you draw when you hear that Mavs center Tyson Chandler is No. 2 in the league this season with 40 alley-oop finishes?

Or that Chandler is second in the NBA in that category behind Dallas’ own LaMarcus Aldridge?

The former Seagoville High star has slammed home 64 alley-oops in Portland, entering Friday’s play, to claim the league lead.

A few more factoids of note from Mavsland entering Friday night’s visit to Boston:

*Jason Kidd has already posted two games this season in which he recorded more than 10 assists without scoring, including a zero-point, 10-assist showing in Dallas’ first meeting with Boston on Nov. 8. Kidd only had two such games in his first 16 seasons.

*Who saw this coming? Nearly 34 percent of Chandler’s points (33.5 percent, to be exact) come from the free-throw line. That’s No. 2 in the league behind Minnesota’s Ramon Sessions (33.9 percent).

*J.J. Barea has drawn 33 offensive fouls this season, good for fourth in the league behind the Celtics’ Glen Davis, Phoenix’s Grant Hill and New Jersey’s Devin Harris.

*The Mavs’ team D has undeniably declined thanks to the disruptions of knee injuries suffered by Dirk Nowitzki and Caron Butler and Chandler’s extended flu bout last month. But when the Mavs held the season’s first 32 opponents below 50 percent from the field, it marked the league’s longest such streak to start a season since Philadelphia in 2001-02.

*Dallas trailed San Antonio by just 1 1/2 games in the West standings after the win in Oklahoma City on Dec. 27 that hiked its record to 24-5 but also left Nowitzki with a sprained right knee. The deficit sits now at 7 ½ games, despite the Mavs’ six-game winning streak.
