Why the Celtics can cover

Guard Jaylen Brown utilizes his athleticism and speed to get to the bucket. Brown gets downhill in a flash and absorbs contact at the rim. The two-time All-Star also has terrific length and quickness on the defensive end. Brown logs 22.7 points, 5.2 rebounds and one steal per game. In the Game 5 win, he notched 22 points, two assists and three steals.

Guard Marcus Smart continues to be a pesky two-way playmaker in the backcourt. Smart plays incredible defense due to his instincts and awareness. The 29-year-old owns good court vision and can knock down perimeter shots. Smart leads the team in assists (5.3) and steals (1.3) with 14.9 points per game during the 2023 NBA playoffs. In his last contest, he racked up 23 points, five steals and went 4-of-6 from downtown. See which team to back here.

Why the Heat can cover

The Heat will be looking to get Jimmy Butler and Bam Adebayo more help in Game 6. Forward Caleb Martin has been a solid scoring option throughout the postseason. Martin owns a solid jumper on the outside and will also put the ball on the deck to attack the lane. The Nevada product is averaging 12.9 points with 4.9 rebounds per game. He has scored at least 14 points and hit two 3-pointers in five straight contests. In Game 4, Martin finished with 16 points and four boards.

Forward Duncan Robinson is another strong shooter off the bench. Robinson is constantly moving without the ball and has a lightning-quick release. The Michigan product dropped 15-plus points in three of his last four games this series. In his last outing, Robinson logged 18 points and nine assists. See which team to pick here.
