How to Use the Boom Promo Code for Thunder-Spurs
With our bonus lineups loaded into our Boom account, it’s time to start doing a little handicapping. Let’s look at the morning line and build an entry using player props from tonight’s showdown at the Frost Bank Center. Here is a look at the consensus over/under lines for the biggest stars stepping on the court:
| Player | Points Over/Under | Assists Over/Under | Rebounds Over/Under |
|---|---|---|---|
| Shai Gilgeous-Alexander | 30.5 | 7.5 | 4.5 |
| Victor Wembanyama | 24.5 | 3.5 | 13.5 |
| Stephon Castle | 18.5 | 6.5 | 5.5 |
| De’Aaron Fox | 14.5 | 4.5 | 3.5 |
| Chet Holmgren | 14.5 | 1.5 | 8.5 |
When I dive into the season statistics, the data reveals some clear advantages depending on how we want to build our Boom entry.
Starting at the top of the board, Oklahoma City’s Shai Gilgeous-Alexander holds the highest point total for the matchup at 30.5 points. However, Gilgeous-Alexander has averaged 28.7 points per game through 10 postseason games. To me, that suggests the under is the smart value play. Similarly, Victor Wembanyama has his points line set at 24.5, but he is averaging 22.1 points per game so far in the playoffs, which also points me toward fading the over.
Conversely, San Antonio’s backcourt provides strong opportunities for the over. Stephon Castle is listed with an 18.5-point prop despite putting up an impressive 20.1 points per game across his 13 postseason appearances. His teammate, De’Aaron Fox, is set at just 14.5 points on Boom but has poured in 18.8 points per game.
Rounding out the top five, Chet Holmgren’s 14.5-point line is noticeably lower than his playoff average of 17.0 points per game. If I’m looking to back the over to build a winning ticket tonight, these three are prime candidates.
