Mavericks vs Thunder Prediction, Picks & Odds (Oct 28, 2026)
By SportsHub Model · Edited by Kyle Parker
The 20-second version
- No edge: our model gives Oklahoma City a 66% win chance, a touch below the 67–70% its -208 to -233 moneyline implies.
- OKC sits Jalen Williams, Chet Holmgren, Alex Caruso and Cason Wallace: 41.3 points per game of production in street clothes.
- Dallas coughs it up 18.5 times a game (26th); the Thunder force 18.8 turnovers a game (4th).
- OKC allows a league-low 100.8 points per game, but Dallas shoots 60.3% on twos (3rd) and Holmgren isn't there to protect the rim.
The Oklahoma City Thunder (4-0) visit the Dallas Mavericks (2-2) at 9:30 p.m. ET Wednesday at American Airlines Center (ESPN). OKC is a 5.5- to 6.5-point favorite and -208 to -233 on the moneyline. The hook: the league's stingiest defense arrives without Jalen Williams, Chet Holmgren, Alex Caruso and Cason Wallace. Our model makes the Thunder a 66% winner, a hair under the market. No edge.
How these teams got here
Oklahoma City hasn't lost, and it hasn't been close often. The Thunder are outscoring teams by 10.5 points a game, allowing a league-low 100.8 points and holding opponents to 41.2% shooting, also first in the NBA. Wins over San Antonio (116-104), Denver (96-84), the Clippers (108-101) and Phoenix (125-114) built that 4-0 start.
The cost came Sunday. Williams fractured his fibula and dislocated his left ankle late against the Clippers, and Wallace tore the labrum in his left shoulder in the same game. Both need surgery and are expected to miss several months. A night later, Caruso left the Phoenix game in the second quarter with a right ankle sprain. OKC still won by 11.
Dallas is 2-2 and has been streaky: a 128-110 loss in Houston, a 121-105 win in Indiana, a 122-106 home loss to San Antonio, then a 113-109 win in Miami on Monday. The Mavs score 112.5 and allow 116.0, a -3.5 net rating that sits 19th. Both teams last played Monday, so neither side has a rest edge.
Dallas ball security vs. the OKC swarm
This game lives in the turnover column. Dallas gives it away 18.5 times a game (26th) with a 16.3% turnover rate (29th). Oklahoma City forces 18.8 turnovers a game (4th). Even Monday's win in Miami came with 17 giveaways, five of them from Cooper Flagg.
When the Mavs do get a shot up, they're efficient. They shoot 49.6% from the field (4th), 60.3% on twos (3rd) and post a .567 effective field goal rate (5th). Flagg leads the way at 25.0 points, 5.3 rebounds and 6.3 assists on 56.5% shooting, and he went for 29 points and 11 assists in Miami. P.J. Washington adds 15.5 points and 7.5 boards.
On the other end, it's Shai Gilgeous-Alexander's show: 27.3 points a game. Ajay Mitchell dropped a career-high 30 points on 10-of-16 in his first start of the season Monday, and Jared McCain is hitting 47.8% from three. Isaiah Hartenstein had 15 points and 13 rebounds against Phoenix and becomes the whole frontcourt without Holmgren.
The injury report decides the margin
OKC's absences add up to 41.3 points per game: Williams 13.7, Holmgren 12.0, Caruso 9.3 and Wallace 6.3. Holmgren (right knee patellar tendinitis) also takes 9.3 rebounds and 3.0 blocks a night with him, which matters against a Dallas team that lives at the rim. Mitchell is questionable with a right ankle sprain; if he sits, the Thunder are down to SGA, McCain and a thin wing group.
Dallas has its own question marks. Kyrie Irving (19.0 points a game) is questionable for left knee injury management, and Naji Marshall (13.7 points, 5.7 assists) is questionable with an illness. Caleb Martin is questionable too, Santi Aldama is doubtful and Dereck Lively II remains out after foot surgery. With no Lively, Daniel Gafford carries the center minutes at 6.0 boards a game.
How the line has moved
The spread has bounced between OKC -5.5 and -6.5 since it went up Tuesday night, and -6.5 is now the most common number. The clearer move is the total, which has slid from 230.5–231.5 to 228.5–229.5. The market is pricing a Thunder team that still defends but has fewer ways to score.
Prediction: no edge
No edge. The reasons:
- The model sits below the market. 66% for OKC against a 67–70% implied price leaves nothing to bet.
- The turnover gap favors OKC. 18.8 forced vs. 18.5 committed is the strongest number in the matchup.
- The injuries favor Dallas. 41.3 points a game and the Thunder's rim protector are out, and Mitchell is questionable.
- Dallas scores inside. A 60.3% two-point rate (3rd) against a frontcourt without Holmgren is a real problem for OKC.
The swing factor is Irving. If he plays, Dallas has two creators against a short-handed defense; if he sits, the Thunder's pressure meets a Flagg-only offense that already turns it over too much.
On the total, OKC games have averaged about 212 combined points and Dallas games about 228.5, against a posted 228.5–229.5. With both offenses missing pieces, the number looks fair, so we pass there too.
