LeBron James continues to defy age, showcasing his scoring prowess during the 2026 NBA Playoffs. At 41 years old, he has stepped up as the primary scoring option for the Los Angeles Lakers, especially with Luka Doncic sidelined due to a hamstring injury. James is currently averaging 25.3 points per game in the series against Houston, and he has scored 28 or more points in his last two matchups with the Rockets. For Game 4, his over/under for total points is set at 23.5, and the SportsLine Projection Model predicts he will exceed this total.

In addition to James, the model is optimistic about Jaylen Brown of the Boston Celtics as they face the Philadelphia 76ers at 7 p.m. ET. Brown has accumulated 14 rebounds over his last two games, with his over/under for total rebounds on Sunday at 5.5. The Celtics hope to secure a 3-1 series lead as Brown is projected to average 7.2 rebounds in this matchup.
