Forward Caleb Martin has been sensational for the Heat in the 2023 NBA playoffs. Martin is coming off his best postseason performance in Miami's victory over the Celtics in Game 2, finishing with 25 points, four rebounds, one block and one steal. He's now scored double-digit points in four of his last five games, but should he be included in your NBA DFS lineups for Game 3 of Heat vs. Celtics?

Martin managed just eight points in Miami's last home game, a 96-92 victory over the New York Knicks. He also registered just five points in Miami's 98-95 victory at home against the Celtics on January 24. With the NBA DFS player pool featuring the likes of Jaylen Brown, Bam Adebayo and Marcus Smart, you'll need to identify which players have the best chance of returning value for your NBA DFS lineups.

Top NBA DFS picks for Sunday, May 21

One part of McClure's optimal NBA DFS strategy includes rostering Heat forward Jimmy Butler. The six-time NBA All-Star seemed content to play a facilitator role during the regular season, but he's made a more concerted effort to take over games during the NBA postseason.

Butler has 62 points, 13 rebounds, 13 assists, nine steals and two blocked shots in the first two games of the series, while giving the Heat a 2-0 lead heading back to Miami. During the 2023 NBA playoffs, Butler is averaging 31.1 points, 6.6 rebounds, 5.6 assists, 2.2 steals and 0.8 blocks, while shooting 51.8% from the floor. Lock him in your NBA DFS lineups and look for a big return against the Celtics on Sunday. 

Another part of McClure's optimal NBA DFS strategy includes rostering Celtics forward Jayson Tatum. Boston is in desperate need of a win, and the Celtics will look for Tatum to lead the charge. The Duke product is coming off an impressive performance in Game 2, recording 34 points, 13 rebounds and eight assists. 

Tatum has scored 30 or more points in each of his last three games, which includes a 51 point outburst in the Game 7 victory over the 76ers. He's also recorded double-digit rebounds in five of his last seven outings, making him a solid building block for your NBA DFS lineups. See the rest of McClure's NBA DFS picks here.
