The arithmetic is almost too neat: Dallas’ reserves scored 43 points, Oklahoma City’s bench scored 19, and the Mavericks won by 24. That does not assign every point of the victory to the reserves, but it captures why Dallas could keep pulling away after Cooper Flagg’s scoring work was finished.
Wednesday’s 120-96 win at American Airlines Center was still close at halftime, when Dallas led Oklahoma City 65-59. The Mavericks built the rest of their margin across the third and fourth quarters. Flagg scored 26 points, Kyrie Irving added 15, and Dallas’ bench supplied enough offense to turn a competitive opening into a controlled finish.
The reserve contribution was especially visible at the beginning of the second quarter. Marcus Sasser found Zaccharie Risacher for a 3-pointer at 11:29, then delivered another 3 to Caleb Martin at 9:55. Risacher’s shot made it 36-30, and Martin’s later three put Dallas ahead 39-34.
Sasser then began adding his own points. He cut for a layup and made the foul shot at 6:52, hit a running 3 at 5:02 and followed with a 15-foot pull-up at 4:10.
That sequence made Sasser more than a spot-up answer. He scored 10 points and had four assists, and his second-quarter work arrived while Oklahoma City was still close enough to threaten. Dallas did not need Flagg to solve every possession. It had another ballhandler who could create a finish, and teammates who completed the baskets from his passes.
Risacher’s night fit the same pattern without requiring a large offensive role. He made five of six shots, scored 13 points and collected four offensive rebounds. At the start of the fourth, he put back a miss at 10:42 and then hit a step-back 3 from Sasser at 10:16, stretching Dallas’ lead from 98-83 to 101-85.
The sequence was valuable because it came after Oklahoma City had already seen Flagg score repeatedly in the third quarter; Dallas’ advantage did not depend on reopening that particular source of offense.
Flagg had scored all 26 of his points through the first three quarters, while also supplying eight assists without a turnover. His passing helped launch several of the game’s early scoring bursts, including two Irving 3-pointers in the first quarter and Daniel Gafford’s 3 at 8:29. Irving also found Max Christie for a 3 in the second and third quarters.
The stars created the structure, but the reserve group kept filling it.
The Thunder did offer a credible objection to any overly tidy bench explanation. Ajay Mitchell scored 29 points on 12-for-20 shooting, and Isaiah Hartenstein controlled the glass with 14 rebounds. Oklahoma City also entered the game without Chet Holmgren, Jalen Williams, Alex Caruso and Cason Wallace.
Its 5-for-32 shooting from 3-point range was unusually poor, and Dallas should not treat one night against a depleted opponent as proof of a permanent defensive transformation.
