San Antonio Spurs vs Oklahoma City Thunder (8:30pm, EST)

Victor Wembanyama Under 24.5 Points (-118) at FanDuel Sportsbook

Since the start of the playoffs, Victor Wembanyama has been unable to recapture the same success he had throughout the regular season, averaging 20.3 Points per game while shooting 34.1% from three and 53.8% from the field.

Even during his cold stretch of play per his standards, the San Antonio Spurs have still been able to remain competitive in their contests, putting away Minnesota in six games.

Unfortunately for the Spurs center, negative regression looms large in their highly anticipated matchup against the Oklahoma City Thunder as he faces off against a defense who currently leads the league in Defensive Efficiency and in Opposing True Shooting Percentage.

With Chet Holmgren capable of face guarding around the perimeter, Wembanyama will have a hand in his face for the full duration of the contest, lowering the quality of his shot attempts.

Chet Holmgren Under 8.5 Rebounds (-109) at Caesars Sportsbook

Speaking of Holmgren, he has been productive in his efforts of crashing the glass, averaging over nine Rebounds per game in the playoffs.

With Wembanyama pulling Holmgren out to the perimeter, expect the Thunder center to see a decline in his total number of Rebound Opportunities as he will be forced to combat against more bodies in the middle, drastically lowering his chances of hauling in a board.

Devin Vassell Under 2.5 Three Pointers Made (-195) at BetMGM Sportsbook

Even with Wembanyama pulling defensive attention away from him, Devin Vassell has been unable to capitalize on the extra space around the perimeter, shooting just 32.3% from three.

With the Thunder allowed to stretch out their guards while single guarding Wembanyama, Vassell will struggle to break away from their coverage, leading to a lower volume of shot attempts from three which improves the likelihood he is held under the total on his Three Pointers Made prop.

Oklahoma City Thunder Team Total Under 113.5 (-115) at BetMGM Sportsbook

On the other side of the court, the Thunder have been nearly just as productive on offense, fielding a lineup who ranks in the top-8 in Adjusted Offensive Rating and in Three Point Completion Percentage.

Their high level of play on both ends helps reduce the amount of negative variance in their contests, making it easier for them to pull away on the scoreboard and secure the win.

Against the Spurs, expect the Thunder to fall hard back down to reality, battling it out against a defense who excels in coverage per their above league average marks in Defensive Efficiency and in Opposing Effective Field Goal Percentage.

For some more exposure, escalator bet the Thunder team total by placing smaller wagers on their alternate unders at the best available odds across multiple sportsbooks.
