The Boston Celtics can complete a historic comeback when they host the Miami Heat in Game 7 of the 2023 Eastern Conference finals on Monday night. No team has ever recovered from a 3-0 deficit in an NBA playoff series, but the Celtics rattled off their third straight victory on a buzzer-beating tip-in after blowing a double-digit lead in Game 6 on Saturday. Meanwhile, Miami can make history by joining the 1999 New York Knicks as the only No. 8 seed to make the NBA Finals. Gabe Vincent (ankle) is questionable for Miami, while Malcolm Brogdon (forearm) is questionable for the Celtics.

Tipoff is at 8:30 p.m. ET from TD Garden in Boston.

Featured Game | Boston Celtics vs. Miami Heat

Why the Heat can cover

Miami won't be fazed by the atmosphere at TD Garden in Boston. The Heat are 2-1 in the building during the series, scoring more than 1.18 points per possession in those three games. Miami has a stellar 33.6% offensive rebound rate in games played in Boston, and the Celtics are also just 5-5 at home during the postseason.

The Heat committed only five turnovers in the game and were 14 of 30 from 3-point range. Miami struggled mightily inside the arc in a way that isn't indicative of talent deficiency, and the Heat are scoring more than 1.16 points per possession in the playoffs.

Why the Celtics can cover

Miami has seen a 3-0 lead dissipate and has to go on the road for Game 7 on Monday night, making this an incredibly difficult scheduling spot for an underdog. The Heat appeared to have clinched a spot in the NBA Finals before Derrick White's tip-in at the buzzer, giving the Celtics all the momentum in this series. Boston held Miami stars Jimmy Butler and Bam Adebayo to a combined 9 of 37 shooting from the floor, as Butler made exactly five field goals for the third time in the series.

Jayson Tatum and Jaylen Brown both posted double-doubles for Boston, while Marcus Smart added 21 points. Tatum has scored 30 points four times in this series, and he will be comfortable playing at home in front of a raucous crowd. The Celtics are 37-14 at home this season, going 29-22 against the spread. See which team to pick here.
