How to Use Your Underdog Bonus Tonight

The Boston Celtics hit the road tonight to take on the Miami Heat. Tip-off is scheduled for April 1, 2026, at 07:30 PM EDT.

Take a look at tonight’s popular player props from both teams to help build your card:

Boston Celtics Props:

• Jaylen Brown: 27.5 Points
• Jayson Tatum: 8.5 Rebounds
• Derrick White:  4.5 Assists
• Payton Pritchard: 16.5 Points
• Sam Hauser: 2.5 3-Point Field Goals

Miami Heat Props:

• Bam Adebayo: 10.5 Rebounds
• Tyler Herro: 22.5 Points
• Andrew Wiggins: 14.5 Points
• Jaime Jaquez Jr.: 13.5 Points
• Davion Mitchell: 5.5 Assists

When evaluating the lines tonight, there are several intriguing statistical trends that point to hidden value. For the Boston Celtics, Jaylen Brown’s points line sits at 27.5, which is just below his season-long baseline as he is averaging roughly 28.5 points per game. Likewise, Derrick White provides solid upside on his 4.5 assists prop as he is averaging close to 5.5 per game. Jayson Tatum has also been a force on the glass since he has returned from his achilles injury.

Looking at the Miami Heat side, Bam Adebayo’s rebound line is set at 10.5. Adebayo averages 10.03 total rebounds per game, but it does stand to reason that he may face stiff resistance on the boards tonight. The Boston Celtics boast a dominant 52.8% total rebound percentage, meaning the under might hold the real value here. Meanwhile, Andrew Wiggins offers steady scoring potential against his 14.5 points line, as he has averaged 15.60 points through 62 games this season.

When you are ready to construct your card, Underdog provides two distinct ways to structure your entries:

• Standard Entry: This option requires 2+ picks and offers the largest potential payout. However, the risk is higher. Keep in mind that all legs must hit in order to win.
• Flex Entry: For those looking for a little more breathing room, you can choose to flex an entry with 3+ picks. While the maximum payout is slightly reduced, this option provides a safety net where you can still receive some winnings even if a leg is incorrect.

Choose the entry style that best fits your analytical strategy!
