How to Use Your Boom NBA Bonus Tonight

If you are looking to put your Boom promo to use for tonight’s marquee matchup between the San Antonio Spurs and New York Knicks, the daily fantasy prop market is loaded with high-value targets.

Here is a look at the lines for the biggest stars taking the floor tonight:

Player	Points	Assists	Rebounds
Victor Wembanyama	27.5	3.5	11.5
Jalen Brunson	26.5	5.5	2.5
Karl-Anthony Towns	17.5	3.5	11.5
OG Anunoby	16.5	1.5	5.5
Stephon Castle	15.5	6.5	4.5

When building your entry, the underlying data suggests some interesting leans and potential longshot value for tonight’s biggest names.

Victor Wembanyama carries the highest scoring projection of the night at 27.5 points, but the projections lean heavily toward the under. This isn’t entirely surprising given the situational context. The Knicks have been incredibly dominant, boasting a massive 16.2 Net Rating and securing 55.0% of available rebounds. With New York’s efficiency and rebounding control, it does stand to reason that Wembanyama could struggle to find second-chance opportunities.

On the home side, Jalen Brunson sits at a 26.5-point total, and the market favors his over. With New York operating at such a high Net Rate, Brunson remains in a prime position to eclipse his point total as the clear engine of the Knicks’ offense.

Meanwhile, Karl-Anthony Towns has a points prop of 17.5. Fantasy players using the promo might want to eye the under. The Spurs have been highly competitive themselves with a 9.8 Net Rating and a 52.2% Total Rebound Percentage. We’ve seen time and time again that a strong interior presence can limit elite bigs, indicating San Antonio has the tools to make Towns work hard for his points tonight.
