Macao Gives the Mavericks a Better Question Than a Preseason Score

Dusty May has defined Dallas’ Houston meetings as opponent-specific tests of offensive adaptability, defensive resilience and a roster still carrying important health questions.

A trip to Macao is partly basketball and partly international business, but the Mavericks’ most valuable souvenir should be a clearer scouting report on themselves.

That was the substance of Dusty May’s Friday message after Dallas’ sixth training-camp practice. Houston’s athleticism, physicality and defensive switchability should expose the Mavericks’ offensive weak points, while the Rockets’ scoring ability will place pressure on a Dallas defense that still has unfinished personnel questions.

The teams meet Oct. 9 and Oct. 11 at Venetian Arena, then face each other again in Houston when the regular season opens for Dallas on Oct. 21.

The useful question is not whether the Mavericks win an exhibition. It is whether they can keep producing sensible offensive choices after Houston removes the first one.

Houston will test the second decision

Switchable defenses are inconvenient because they refuse to cooperate with an offense’s preferred matchup. A screen does not automatically create a lumbering defender to attack, and a favorable post touch can disappear before the ball arrives. Dallas will need timing, movement and quick reads when the obvious advantage is denied.

That makes Daniel Gafford’s development more relevant than any isolated shooting number. On Friday, the center said he is willing to take occasional rhythm 3-pointers when the possession earns the attempt. He also acknowledged that the first shots may feel unfamiliar and require confidence.

Gafford has made only one 3-point attempt in seven NBA seasons, so this is a modest experiment, not a sudden change in identity.

His established work remains near the rim. Extra spacing would be useful only if it complements the screening, rolling and finishing that already make him valuable. Against Houston, the important sequence may be what follows a switched screen—whether Gafford relocates, seals a smaller defender or makes the next pass—rather than whether a single perimeter attempt drops.

May’s broader offensive test reaches beyond the center. He said Zaccharie Risacher made excellent decisions in roughly five open-court situations during Friday’s practice, pointing to improved changes of speed, driving-and-kicking reads, lane-running, offensive rebounding and open-shot making. Those were coaching observations from practice, not game statistics.

Still, Houston’s pressure should reveal whether those decisions remain available when defenders are stronger, possessions are less scripted and the first drive stalls.

The defensive answers remain conditional

Dallas cannot fully judge that matchup until it knows which bodies can participate. Morez Johnson Jr. played extensively in 5-on-5 work Friday after a gradual return from lower-leg soreness. His progression had been measured earlier in the week, making the larger workload a meaningful step in evaluation.

It does not establish that he is ready for unrestricted duty, and Dallas has not announced his Macao status.

Santi Aldama’s situation is also unresolved as he recovers from March arthroscopic surgery on his right knee. Dereck Lively II remains on the recovery path from December foot surgery. Those are potential lineup changes, not confirmed absences, but they matter because Houston’s offensive skill can expose thinness at several defensive positions.

May wants to learn which Dallas options can withstand physical possessions; the answer will be less reliable if key frontcourt pieces are unavailable or limited.

Johnson’s case carries an additional wrinkle. The ninth pick in June played for May at Michigan during its 2026 national-championship run, so he already knows the coach’s terminology and practice habits. That familiarity may shorten the teaching curve. It cannot substitute for NBA-level strength, pace or spacing, and Friday’s live-work increase supplies evidence of participation rather than proof of readiness.

The Macao games should give Dallas two different tests. Houston’s switching can expose whether the Mavericks have enough connective passing and patience to reach a second advantage. Houston’s offense can identify which defenders hold up when the game becomes physical. Meanwhile, Johnson, Aldama and Lively’s statuses will determine how much of that defensive picture is complete.

The scoreboard will travel home easily. The better return is a shorter list of offensive actions Dallas trusts, a clearer sense of its defensive combinations and a better distinction between a combination that failed and one that could not yet be tested.
