Totals for Game 4 in San Antonio
Let’s get to the fun part: handicapping the board. With your bonus secured, it is time to build a winning slip for tonight’s game. The Boom platform offers a wide variety of player props, but I always look at the biggest stars first because that is where we can often find the clearest data. Below is a look at the five players with the highest consensus over/under point totals for the matchup.
| Player | Points Over/Under | Assists Over/Under | Rebounds Over/Under |
|---|---|---|---|
| Shai Gilgeous-Alexander | 29.5 | 7.5 | 3.5 |
| Victor Wembanyama | 24.5 | 3.5 | 13.5 |
| Stephon Castle | 16.5 | 6.5 | 5.5 |
| De’Aaron Fox | 14.5 | 5.5 | 3.5 |
| Chet Holmgren | 13.5 | 1.5 | 7.5 |
When we compare these lines to what these guys are actually doing in the postseason, a few clear betting angles emerge. I’m placing my entries based on the math, and right now, the data tells us to fade a couple of stars.
Oklahoma City’s Shai Gilgeous-Alexander carries the highest points prop at 29.5, but he is currently averaging 28.5 points per game. Because his line sits a full point above his postseason production, the smart money leans toward the under. Similarly, Victor Wembanyama’s 24.5 points line feels a bit inflated; the Spurs big man is averaging 22.4 points per contest, making the under a statistically sound choice.
On the flip side, we have a real chance to capitalize on a pair of San Antonio playmakers. Stephon Castle boasts a point total of 16.5, yet he is pouring in 19.6 points per game. De’Aaron Fox offers an even wider gap, with a 14.5 point total despite averaging 18.5 points so far this postseason. Based on the hard numbers, both Castle and Fox are well-positioned to clear their points projections tonight.
