This preseason finale is really two games stacked on top of each other. The first half is starters against starters, and on paper that phase looks close to even. The second half belongs to the benches, and that is where these two rosters split apart. Who plays the minutes after the break matters more than either team's name or preseason record.
Both preseason records follow from who played. Houston's full starting five (VanVleet, Thompson, Durant, Smith, Sengun) logged about 21 to 24 minutes each and won comfortably at Dallas. With Durant, VanVleet and Sengun rested, the same team lost at home by double digits. Oklahoma City has used a split plan all preseason: Gilgeous-Alexander, Jalen Williams and Wallace around 18 to 23 minutes, then a long stretch for a rookie and two-way group. That group lost two home second halves by about twenty points each.
The key matchup in the opening half is size against pressure. Oklahoma City's guards want turnovers and early offence. Houston answers with Sengun at the elbow and a lot of offensive rebounding, against a Thunder frontcourt where Holmgren has not played a preseason minute and the rookie Mara has struggled against bigs who step out. I expect that phase to stay within a few points either way.
The absences shift the second half. Oweh is out for the season, and the summer departures already thinned the Thunder's depth. That leaves Stirtz, Dix, Barnhizer, Pritchard and Holifield auditioning against Smart, Bogdanovic, Eason, Sheppard and Adams or Capela, who are real rotation veterans. In the Dallas win, Eason and Sheppard carried exactly those bench minutes.
The flow I expect: an even first half, then the turning point early in the third quarter when Oklahoma City's starters sit for good. If their young tier takes those minutes, as it has all preseason, Houston's bench should build the margin through the third and fourth quarters. McCain's shooting is the Thunder's best way to break that pattern, but one hot night is not a structure.
Houston's starters are listed as probable and have been named the projected five, with nothing new ruling any of them out. With the starters roughly even and the bench gap clearly in Houston's favour, I'm siding with the Rockets to win at home.
