The Mavericks opened the preseason slate at home against Houston and lost 117-135, with Cooper Flagg scoring 19 points on a team-worst -15. The numbers around it -- a bench that nearly matched the starters, a payroll sitting under the tax threshold, and last season's -5.2 net rating -- frame where Dallas stands before the October 21 opener at Houston.

A Lopsided Opener
Houston broke this one open early and never let go. The Rockets strung together bursts of 9-0, 10-0 and 10-0 across the first two quarters, building a 28-point cushion Dallas never threatened. Cooper Flagg led the Mavericks with 19 points on 7-for-14 shooting and four made free throws, but he finished -15 in just 19 minutes. Alperen Sengun ran Houston's offense from the five spot, posting 16 points, 10 rebounds and 10 assists, a step below last season's 20.4-point, 8.9-rebound averages but plenty to control the game.
Bench Nearly Matched The Starters
Dallas starters scored 62 points; the bench answered with 55. Tobi Lawal was the most efficient Maverick on the floor, going 5-for-6 for 13 points and finishing +2, the only Dallas player on the plus side. Sergio de Larrea added 11 points and 6 assists in 24 minutes. Naji Marshall and Zaccharie Risacher each finished -13, and Max Christie hit 4 of 11 from three for 14 points in a losing effort.
Payroll And Net Rating
Dallas carries $197.9 million in payroll, over the salary cap but under the $200.4 million luxury threshold, with Kyrie Irving's $39.5 million deal the largest number on the books ahead of P.J. Washington's $19.8 million and Klay Thompson's $17.5 million. Last season's team finished at a -5.2 net rating, 110.3 on offense and 115.5 on defense, 22nd of 30 leaguewide. Five players are sidelined heading into the next test -- Lively, Sasser, Washington, Martin and Aldama -- each with an estimated return of October 11, two days before Dallas visits Houston again.
