NBA Player Props via Sleeper Tonight

Looking to extract some value from tonight’s Celtics vs. Warriors matchup? Here are the top five players with the highest projections available on the board:

Player Points Assists Rebounds
Jaylen Brown 24.5 5.5 6.5
Jayson Tatum 21.5 4.5 7.5
Derrick White 15.5 4.5 4.5
Payton Pritchard 15.5 4.5 3.5
Brandin Podziemski 14.5 3.5 6.5

Tonight’s game features some intriguing situational angles, particularly with Golden State navigating a massive injury report. With Stephen Curry sidelined due to a lingering knee issue and Jimmy Butler out for the season following an ACL tear, the Warriors will have to rely heavily on their depth against a Boston squad boasting a dominant 6.6 net rating.

When we put a lot of stock into the data for your entries, a few clear trends emerge. For Jaylen Brown, despite holding the highest point projection of the night at 24.5, the underlying metrics might lean toward him finishing with less than that total. Brown has been phenomenal this year, but he is currently adjusting his usage to accommodate Jayson Tatum, who recently returned from an Achilles injury.

On the Golden State side, one player to highlight is Brandin Podziemski. Stepping into a massive offensive void, the third-year guard has embraced his role, dropping 25 points in each of his last two games. His points projection sits at a modest 14.5, but he has been great recently. Without Golden State’s primary offensive engines available, it stands to reason that Podziemski will easily see the necessary volume to eclipse his total, making him a fantastic foundational piece for tonight’s Sleeper entries.

How to Activate the Sleeper Promo Code MHSXL

Ready to lock in your entries before the 07:00 PM EDT tip-off? Getting started is a straightforward process. Follow these steps to claim your welcome bonus:

First, you will need to create and register a new account by providing standard personal information. During this sign-up process, entering promo code MHSXL is absolutely required to successfully activate your promotional value.

Once your account is verified, you must make a deposit of at least $10 using one of Sleeper’s secure payment methods. Simply making this qualifying minimum deposit is enough to trigger your instant $20 sign-up bonus.

However, we highly recommend planning ahead, as the second half of this promotion only applies to your first deposit. Sleeper will match this initial transaction 100%, meaning you shouldn’t just deposit $10 unless $10 is all you want matched.

To receive the absolute maximum $120 value of this Sleeper bonus ($20 sign-up bonus plus the $100 match), you must make a first-time deposit of $100. It is important to note that you do not have to deposit the full $100 to take advantage of the match. The promotion scales entirely to your comfort level—for example, if you deposit $50, Sleeper will match it with an additional $50. Just be sure to choose your initial deposit amount carefully so you have the exact capital you need to tackle tonight’s Boston vs. Golden State matchup.
