Spurs vs. Thunder Prediction

San Antonio took four of the five meetings in the regular season this year, including a 111-109 win in the semifinals of the NBA Cup in Las Vegas. The Thunder has home court and the rest advantage, having a week off to San Antonio’s two days of rest. Oklahoma City has the MVP, as Gilgeous-Alexander was named the winner of the award Sunday. They also have Williams returning after missing the last six games with a hamstring injury. Still, it’s hard to count out San Antonio, especially with the mismatches that Wembanyama creates. Oklahoma City is dominant but the Spurs aren’t intimidated. Take the points and the visitors here.
