💰 Best Spurs vs. Mavericks player props
Our NBA player prop odds tool shows the best odds for every market across legal sportsbooks in your area.
⬇️ Victor Wembanyama Under 24.5 points (-109) ⭐⭐⭐⭐
Wembanyama makes his return after being shut down in January last season with deep vein thrombosis in his right shoulder.
While he averaged 24.3 points per game last season, there’s a good chance he underperforms in his return from injury. In the Spurs’ season opener last year - also in Dallas - Wembanyama scored 17 points on 5-of-18 shooting from the field. The Mavericks are among the bigger teams in the NBA, and the combination of Anthony Davis and Dereck Lively II should be enough to keep Wembanyama under this total.
DraftKings has the best odds at time of publish for Wembanyama to go Under 24.5 points. These -109 odds carry an implied probability of 52.15%, with a winning $10 bet profiting $9.17.
⬇️ Cooper Flagg Under 1.5 blocks (-179) ⭐⭐⭐⭐
While -179 odds are pricier than the traditional -110 on the spread, this price is too good to pass up.
Cooper Flagg to record Under 1.5 blocks in his NBA debut should be priced closer to -215. The 6-foot-9 rookie averaged 1.4 blocks in college, and that was obviously against much smaller and less athletic competition. Additionally, he recorded a total of just three blocks across his four preseason games.
The -179 odds for Flagg to go Under 1.5 blocks at DraftKings are the best odds at time of publish. These odds have an implied probability of 64.16%, and a winning $10 wager would profit $5.59.
⬆️ Stephon Castle Over 5.5 assists (-130) ⭐⭐⭐
Stephon Castle averaged just 4.1 assists per game in his 2025 Rookie of the Year-winning campaign, but that number should jump dramatically this season.
Castle wasn’t an immediate playmaker when he came to the NBA, but he grew into that role over time. He averaged 7.5 assists per game in April to close out last season and recorded six or more assists in six of eight games that month.
BetRivers' -130 odds for Castle to go Over 5.5 assists are the best available at time of publish. These -130 odds carry an implied probability of 56.52%, and a winning $10 bet would profit $7.69.
