The Los Angels Lakers and Boston Celtics are two of the oldest teams in the NBA and have the most passionate rivalry in the league. Despite the absence of Jayson Tatum, Jaylen Brown and Boston are the No. 2 seed in the East. The Lakers are in the middle of the playoff race in the West with their superstar duo. Here's how I see this game playing out:
| Player | Team | Pick |
| Jaylen Brown | Boston Celtics | Higher Than 6.5 Rebounds |
| Luka Doncic | Los Angeles Lakers | Higher Than 29.5 Points |
| LeBron James | Los Angeles Lakers | Lower Than 20.5 Points |
I like Brown to corral a large number of rebounds, as he's been excelling in this role as of late. I expect Doncic to score at a high volume because he's done so through most of the season, averaging 32.8 points per game. Finally, I expect James to have to make an impact in other ways in the game outside of scoring. Not to mention, Boston is a tough defense to go up against.
