The Cleveland Cavaliers travel to face the Los Angeles Lakers in a highly anticipated matchup that tips off on March 31, 2026, at 10:30 PM ET. With both teams deep into their regular-season schedules, we put a lot of stock in the robust seasonal data available to help us identify value in tonight’s market.

Here are some of the most popular player props available for tonight’s game:

Cleveland Cavaliers:

• Donovan Mitchell: 24.5 Points, 5.5 Assists, 2.5 3-Point Field Goals
• James Harden: 20.5 Points, 7.5 Assists, 4.5 Rebounds
• Evan Mobley: 16.5 Points, 8.5 Rebounds, 2.5 Assists
• Sam Merrill: 12.5 Points, 2.5 3-Point Field Goals, 2.5 Rebounds
• Jarrett Allen: 11.5 Points, 6.5 Rebounds, 1.5 Assists

• Rui Hachimura: 9.5 Points,  2.5 Rebounds,  1.5 3-Point Field Goals

When looking to build a slip, it does stand to reason that we put a lot of stock in season-long averages to find underlying value. For the Los Angeles Lakers, Luka Doncic’s points prop is set at 31.5. Through 62 games this season, he is averaging over 33.5 points per game—making his over an incredibly appealing consensus projection.

On the other side of the floor, the Cleveland Cavaliers offer massive value with Donovan Mitchell and Evan Mobley. Mitchell is staring down a 24.5 points line, but he is averaging a clean 28.0 points per game this regular season. Down low, Mobley’s rebounding line sits at 8.5 while averaging over 9 rebounds per game.

• Standard Entry: By building a slip with 2+ picks, you can trigger the largest potential payout. However, keep in mind that every single leg in a Standard entry must hit for you to win.
