Heat 105, Celtics 100

Money line

BET MIAMI (-130) to win Game 1.

The Heat are the best 3-point shooting team in the NBA. They led the league in 3-point shooting percentage (37.9 %) during the regular season. Plus, they ranked 2nd in defensive 3-point percentage, holding opponents to 33.9%.

The Celtics won Games 6 and 7 of their previous series because they crushed the Bucks in 3-point differential, but the percentages favor the Heat from behind the arc in this matchup.

The Heat allowed the fewest paint points per game during the regular season. Tucker, SF Jimmy Butler and C Bam Adebayo have the length, athleticism and versatility to frustrate Celtics SF Jayson Tatum and SG Jaylen Brown.

Miami comes in well-rested, whereas Boston just finished a physical 7-game series Sunday vs. a much harder opponent and the Celtics could be fatigued.

The Heat are 19-6 SU with a plus-9.0 margin of victory with a rest edge and 4-0 SU with a plus-23.8 margin of victory with four or more rest days. The Celtics are 10-12 SU when playing with a rest disadvantage.

Miami performs well on extended rest because it allows additional time for coach Erik Spoelstra to devise a game plan and the Heat’s banged-up roster to recover from nagging injuries.

BET MIAMI (-130).
