Spurs vs. Thunder Prediction
The Thunder and Spurs are the No. 1 and No. 2 seeds in the Western Conference, respectively. San Antonio won the season series 4-1, as their size and style of play proved to a perfect counter to the Thunder. NBA MVP Shai Gilgeous-Alexander and third-place finisher Victor Wembanyama highlight the star power that takes the court in this game tonight.
