In the closing minute of the first quarter, Alperen Sengun assisted a Kevin Durant dunk. After Dallas missed at the other end, Sengun assisted another dunk, this time by Amen Thompson. Houston finished the period ahead 32-26.
Those were two of Sengun's five assists in the Rockets' 128-110 win over the Mavericks on Wednesday. The center's own 23 points and ten rebounds made the rest of his line substantial enough that the passing could easily become an afterthought. For Dallas, it should be part of the problem to examine.
Sengun contributed in several different portions of a possession. He made nine of fifteen field-goal attempts, including both of his threes. He collected five offensive rebounds, and he supplied those five assists. Dallas was facing a productive scorer who also helped teammates score and secured additional chances after misses.
The first-quarter finish gives that range some specific shape. Durant's dunk came with 36 seconds remaining. Dallas then missed a Marshall three before Thompson's dunk with roughly 22 seconds left. Sengun received an assist on each Houston basket. It was productive passing on separate trips, rather than one vague claim that the entire offense ran through him.
His outside attempts added another successful element. Sengun made a three in the first quarter and another in the third. Two attempts are a small sample, but two makes still require a defense to account for the points actually scored. Dallas could not assess his night solely through what happened close to the basket.
His rebounding created a different burden. Five of his ten boards came on offense, helping Houston reach seventeen offensive rebounds overall. The Mavericks collected eight at that end. When an opponent secures its own miss, Dallas has another defensive task before it can begin the next attack.
Sengun was not alone in doing that work. Thompson had six offensive rebounds as part of his own ten-rebound performance. That is an important qualification to the center-focused account: Houston's second chances were a collective achievement, and Dallas cannot assign every failed defensive possession to one matchup between big men.
The opponent's other scoring made the combined job harder. Jabari Smith Jr. finished with thirty points, a total Durant matched. Sengun's 23 gave Houston a third substantial source of points. Dallas was therefore dealing with productive contributions in several places, rather than one scorer surrounded by a quiet supporting cast.
That does not mean every defensive choice was equally difficult or that any particular coverage was wrong. The scoring and passing record does not establish the precise Dallas assignments. It does establish that Houston received more than finishing from its center, and that a response focused only on reducing his point total would leave other successful contributions unaddressed.
