Celtics-Cavs Player Prop Entries via Sleeper

When we look at the projections for this game, the lines are telling an interesting story. We’ve seen time and time again that injuries and recent returns create market inefficiencies, and this game is no exception. Below are the consensus prop totals for the top five players involved in this Eastern Conference battle.

Player	Points	Assists	Rebounds
Donovan Mitchell	25.5	5.5	3.5
Jaylen Brown	25.5	4.5	6.5
Jayson Tatum	16.5	4.5	6.5
Derrick White	15.5	5.5	3.5
Evan Mobley	15.5	2.5	8.5

Prop Analysis and Matchup Notes

The number that immediately jumps off the page is Jayson Tatum at 17.5 points. It stands to reason that the books are being cautious given his recent return from a long-term Achilles injury. However, for a player of his caliber who just logged meaningful minutes against Dallas, this line feels like a massive value spot.

On the Cleveland side, Donovan Mitchell is listed at 25.5 points. While he is the engine of that offense, the “probable” tag due to a groin injury is a red flag we can’t ignore. Soft tissue injuries can limit explosiveness, and against a stout Boston perimeter defense, he has a tall task today.

We also need to give a shoutout to Evan Mobley. With Jarrett Allen out of the lineup, Mobley is going to have to shoulder the load in the paint. His points line is 16.5, but his rebounding total of 9.5 is where the opportunity lies. Without Allen fighting him for boards, Mobley’s volume should increase significantly.

How to Activate Your Sleeper Promo Code BROADXL

Getting set up with Sleeper before the 1:00 PM ET start time is simple. Follow this process to ensure you lock in the maximum bonus value with code BROADXL.

1. Download and Register: Get the Sleeper app or head to their site. You’ll need to provide standard personal details to verify your identity.
2. Enter the Code: This is the crucial step. Enter promo code BROADXL when prompted to unlock the full welcome package.
3. Make Your First Deposit: Deposit at least $10 through a secure method to activate the account.

Strategic Deposit Advice:
While the $10 minimum triggers the automatic $20 bonus, we always advise maximizing the value on the table. Sleeper’s 100% deposit match only applies to your first transaction.

• Maximize the Value: To secure the full $120 in total bonuses ($100 match + $20 instant bonus), your first deposit should be $100.
• Flexible Options: You aren’t forced to go for the max. If you deposit $50, you get a $50 match.
• Don’t Shortchange Yourself: If you stick to the $10 minimum, you get the $20 bonus but only a $10 match, leaving $90 of potential value behind.

Once funded, your bonuses hit your account instantly, ready for you to make your picks on the Celtics vs. Cavaliers matchup.
