The 2026-27 NBA season is off to a strong start, and Wednesday night brings a classic Texas showdown as the Dallas Mavericks travel to Toyota Center to face the Houston Rockets in a Southwest Division matchup at 8:30 p.m. ET. Houston is favored by 9.5 points on PrizePicks.

Dallas finished last season 26-56 and missed the postseason despite an encouraging rookie campaign from F Cooper Flagg. Houston, meanwhile, went 52-30 to secure the Western Conference's fifth seed before falling to the Los Angeles Lakers in the first round of the playoffs.

Can Flagg and the Mavericks pull off an opening-night road upset, or will F Kevin Durant and the Rockets take care of business at home and begin their season with a statement victory?

Both teams made notable offseason changes. Dallas enters its second season with Flagg as the centerpiece of its rebuild, while PG Kyrie Irving returns to the lineup to give the Mavericks another proven offensive creator.

The team also added former top overall pick F Zaccharie Risacher and rookie PF Morez Johnson Jr., and brought in former Michigan head coach Dusty May.

In other news, Houston aims to turn another successful regular season into a deeper playoff run. The Rockets added veteran guards Marcus Smart and Bogdan Bogdanovic while also welcoming back PG Fred VanVleet after he missed all of last season with a torn ACL.

Durant, C Alperen Sengun, and PG/SF Amen Thompson remain the foundation of a roster that has the talent to compete with the Western Conference's best.

The Rockets finished last season with a 118.6 offensive rating (eighth) and a 113.2 defensive rating (sixth). Their +5.4 net rating ranked sixth leaguewide, reflecting their ability to compete on both ends of the floor.

By comparison, Dallas finished with a 111.2 offensive rating (27th) and a 116.5 defensive rating (20th).

The good news for Dallas is that Flagg has already demonstrated the ability to carry a substantial offensive workload. With Irving back to help shoulder the playmaking responsibilities, the Mavericks have a chance to take a meaningful step forward.


Mavericks vs. Rockets Prediction on Spread – 10/21/26

Here are the key stats and predictions behind our Mavericks vs. Rockets pick against the spread for Wednesday, October 21.

Unless otherwise noted, data used in this article is from Basketball-Reference, NBA.com, and StatMuse.

  • Houston went an NBA-worst 18-26-0 (40.9%) against the spread (ATS) at home last season.
  • Irving’s addition to the Mavericks' lineup is by far the most significant change for either team. His presence will take pressure off Flagg as the main creator and may open up the offense drastically.
  • Houston was efficient offensively last season but still ranked 18th in overall points per game. This is because their slower pace (96.1 possessions per game, 29th) created fewer opportunities to build a massive margin.
  • The season series was split 2-2 last year, so Dallas has shown it can compete with Houston even without Irving.
  • In Houston’s two wins, it failed to cover this spread, winning 110-102 and 101-97.

Mavericks vs. Rockets Picks, Player Stats for PrizePicks: 10/21/26

Here are two Mavericks vs. Rockets player picks to consider on PrizePicks, featuring Cooper Flagg and Kevin Durant.

Mavericks F Cooper Flagg vs. Rockets: 33.5 Pts + Rebs + Asts

  • Flagg averaged 32.2 combined points, rebounds, and assists (PRA) last season, paired with an impresive 26.9% usage rate.
  • Irving's return should give Flagg better opportunities rather than forcing him to create everything for himself. Irving's ability to handle the ball and draw attention could free up driving lanes, too.
  • Flagg is much more than just a scorer, as his PRA mark was partially made up of 6.7 rebounds and 4.5 assists per game in 2025-26.
  • Thompson is a good defender but still posted a 110.4 defensive rating last season (ninth of 16 players on the Rockets), while Durant and Jabari Smith posted respective figures of 112.4 (14th) and 112.0 (13th).

Rockets F Kevin Durant vs. Mavericks: 33.5 Pts + Rebs + Asts

  • Durant averaged 36.3 PRA last season and now faces one of the league's worst defenses.
  • Durant’s efficiency is a big plus. He shot 52.0% from the field and 41.3% from beyond the arc, so he can score without needing excessive attempts.
  • This is an awesome pace-up matchup for the Rockets against the Mavericks, who owned the fourth-quickest tempo in the NBA last season.
  • KD may be guarded often by Flagg, who owned a 114.7 defensive rating (16th out of 23 Mavericks players) a season ago.
  • VanVleet could fill the major void from last season of offensive creation from a guard. Additionally, the Mavericks will be without anchor C Dereck Lively II, who led them in defensive rating last season (102.7).
Add Kevin Durant + Rockets to cover the spread to your PrizePicks lineup now.
