NBA Playoffs picks, best bets for Wednesday, May 20

Spurs +6.5

The Spurs were road underdogs in Game 1, but they covered and won outright in one of the NBA's most hostile environments. They're now 3-1 overall at Oklahoma City this year, and for context, the Thunder have lost just eight total times at home between the regular season and playoffs. The model has the Spurs covering in roughly half of simulations for Game 2 after Monday's thrilling Game 1 victory. 

Spurs-Thunder Under 216.5

These were two top-eight scoring defenses in the regular season, and while the Over hit in Game 1, that was thanks to not one, but two overtimes. It was 101-101 once the fourth quarter ended, and was just 108-108 after the first overtime. The total is down from Game 1's 221.5 mark, but the model is still leaning Under, with that side hitting in more than 60% of simulations.  

Victor Wembanyama Over 24.5 points

Game 1 of the Western Conference Finals was the "Wemby Show," as San Antonio's superstar big man absolutely took over, scoring a game-leading 41 points while pulling down 24 rebounds. He was far and away the biggest reason the Spurs have a 1-0 lead in this series. It was also far and away his best scoring performance against the Thunder, as his season high in the regular season against OKC was 22. The model expects Wembanyama to be a scoring factor again in Game 2 with a projection of 25.7 points.
