Oklahoma City has allowed 104.2 points per game through 10 games, the NBA's lowest average. Portland faces that defense without Ja Morant and Shaedon Sharpe.
The Thunder are also without Jalen Williams and Chet Holmgren.
Under 227.5 against the Trail Blazers rests on that defense and Oklahoma City's full-game scoring record: 7 of its first 10 games finished below this total.
