Why the Celtics can cover

Boston battled to the end Friday night and held the lead in the fourth quarter, but the Celtics couldn't stop Butler. Boston will be much more focused on that task Sunday, and it held him to 19 total points over the previous two games. The Celtics' top scorers started Game 6 hot, with Tatum and Jaylen Brown each scoring 18 on a combined 12-of-18 shooting. In the second half, they combined for 14, making three of seven shots and six free throws. They should be much more involved throughout Sunday. Tatum averaged 27.1 points and Brown added 22.9 in the regular season.  

Derrick White exploded off the bench Friday, scoring 11 of his 22 points in the fourth quarter, and should be a big help for a team with several players hobbled. The Celtics are 32-16-1 against the spread in road games, 17-7 as a favorite, and they have the better numbers in this series. They are shooting five percent better than Miami, scoring 5.5 points more per game and averaging four more rebounds.  

Why the Heat can cover

Miami is 20-10 against the spread this season as an underdog (4-2 at home) and 10-7 ATS in this postseason. Butler showed Friday night that he can simply take over a game, and he will be pushed hard by the home crowd. Butler averaged 21.4 points in the regular season and is at 26.9 for the series. His 47 points Friday were his career postseason high. Miami led the league in 3-point shooting (37.9 percent), but is hitting just 31.5 percent in the series.

The Heat also have been strong on the defensive end all season. They were fourth in the NBA in both scoring defense (105.6 points per game) and opponent field-goal percentage (44.7) in the regular season. Center Bam Adebayo also is due for a big game, as he is averaging 13.3 points, well below his 19.1 season average, and two fewer rebounds (10.1-8.0).
