What changed
Dallas’ first regular-season test under Dusty May lasted one competitive quarter before Houston tore the game open. The Rockets outscored the Mavericks 38-12 in the second and won 128-110, handing May a loss in his NBA coaching debut.
The collapse joined bad offense to bad transition defense. Dallas went 4-of-19 from the floor and missed all 14 of its threes in the quarter, while Houston made 13 of 19 shots and reached halftime with 20 fast-break points. The Mavericks trailed by 32 at the break and by as many as 37.
Cooper Flagg still finished with a game-high 32 points on 10-of-17 shooting. Marcus Sasser scored 17 off the bench and Kyrie Irving had 15 in 24 minutes, but the late production could only narrow a game already lost. Friday at Indiana, the useful response is not a hotter shooting night alone; it is whether Dallas can keep its offense organized and its transition defense connected when a run turns against it.
OUR INTERPRETATION
Why Dallas fans care
Interpretation: one game is not a verdict on May’s system, but the second quarter exposed the exact chain Dallas cannot allow—rushed or empty possessions feeding easy offense at the other end. The first adjustment to watch is composure, not a wholesale rotation rewrite.
