Why the Mavericks can cover

The entire Mavs offense is run through guard Luka Doncic. Doncic has such a high basketball IQ with a reliable perimeter jumper to space the floor. The five-time All-Star ranks first on the team in scoring (29), rebounds (9.7), assists (8.5), and steals (1.8) in the postseason. In his last outing, Doncic finished with 32 points, 11 rebounds, and 11 assists.

Center Daniel Gafford provides Dallas with an athletic and bouncy scorer in the lane. Gafford can finish through contact and is always a threat for lobs. The Arkansas product is logging 9.4 points, 5.9 rebounds, and 1.6 blocks in the 2024 NBA playoffs. In Game 2, he racked up 13 points, nine rebounds, and went 6-of-9 from the floor. See which team to pick here.

Why the Celtics can cover

Guard Derrick White is a two-way impact player who contributes across the board for Boston. After making his second All-Defensive team in the 2023-24 season, White is averaging 2.0 steals and 1.0 blocks in the Finals, to go along with 16.5 points. He is a big reason for Irving's struggles from the field, and White is also knocking down 40.4% of his 3-point attempts in the 2024 NBA playoffs.

Center Al Horford is a veteran contributor who is able to stretch the floor due to his perimeter jumper, and he fights on the glass. The 38-year-old has scored in double figures in six matchups this postseason. In Game 1, he notched 10 points, seven boards, and made two 3-pointers. See which team to pick here.
