As the 2026 NBA Playoffs heat up, prop betting has gained traction, spotlighting stars like Jaylen Brown of the Boston Celtics. On April 21, Brown has been on fire, scoring 26 or more points in 11 of his last 12 games, averaging 28.7 points per game during the regular season, ranking fourth in the NBA. The SportsLine Projection Model supports Brown to exceed his scoring total of 25.5 points in the upcoming game.

In addition to Brown, the model also favors Jabari Smith Jr. of the Houston Rockets to excel against the Los Angeles Lakers at 10:30 p.m. ET. After pulling down 12 rebounds in Game 1, Smith Jr. is projected to surpass his over/under of 6.5 rebounds.

Before finalizing your bets for Tuesday, consider these top player prop picks backed by the model:

• Jaylen Brown, Celtics: Over 25.5 points
• Stephon Castle, Spurs: Over 7.5 assists
• Jabari Smith Jr., Rockets: Over 6.5 rebounds

Jaylen Brown showcased his scoring ability with 26 points in Boston's Game 1 victory against the Philadelphia 76ers. The model predicts he will score an average of 28.4 points in Game 2.

Stephon Castle, despite a rough shooting night in Game 1, recorded seven assists and has averaged 9.2 assists over his last 14 games. Playing in San Antonio, where he averaged 7.6 assists this season, Castle is positioned for another strong performance.

Jabari Smith Jr. has been a reliable rebounder, finishing with at least six rebounds in six of his last eight games. The model forecasts he will average 7.6 rebounds in Game 2, following his impressive performance in Game 1.
