Just hours before the Boston Celtics started their Eastern Conference Finals series against the Miami Heat on Tuesday at FTX Arena, the team announced that two-fifths of their lineup wasn't going to suit up. Marcus Smart, who was recently named Defensive Player of the Year, suffered a midfoot sprain during Game 7 of the East semifinals on Sunday, and veteran Al Horford surprisingly entered the league's COVID-19 health and safety protocols.
Consequently, the shorthanded Celtics weren't able to fend off the Heat for all 48 minutes. Behind a stellar 41-point performance from veteran swingman Jimmy Butler and second-half offensive surge, Miami defended home court, claiming Game 1 with a 118-107 victory. Boston was outmuscled in a lopsided third quarter, and first-year coach Ime Udoka admitted to reporters they were "out-toughed." The Celtics controlled the first half with ease, but it didn't last.
"Game 1 was set up for Miami to win it, and they did a good job. And they took advantage of it with homecourt," former Celtics executive and current Audacy NBA insider Ryan McDonough told the Reiter Than You show on Wednesday. "Butler had a historically good performance. And that's one thing not getting enough attention, nationally. We focus on Giannis, Luka, and Jayson Tatum --they're terrific players. No one's played better than Butler in this postseason.
"There are clear paths for the Celtics to get better. I think Boston will win the series if Horford comes back relatively soon. He's a very important player for them. If they get Horford, Smart back, and get rested. Just had a hard-fought series against the defending champion... Last night was set up for Miami. But part of that was the Celtics running out of gas -- just given what they've been through over the last couple weeks... I expect the Celtics to bounce back."
Celtics star duo Jayson Tatum and Jaylen Brown scored 53 combined points in Game 1, but their production was overlooked by their third-quarter swoon. Boston scored only 14 points and shot 13-percent from the floor, their worst field-goal percentage in any quarter over the last four years. It also took the team seven-plus minutes to connect on its first bucket, and they committed eight turnovers -- as many as it had in the other three quarters combined.
Boston, which clinched the East's second seed with a 51-31 record, will play Game 2 against Miami on Thursday night (8:30 p.m. ET tipoff). According to FiveThirtyEight's projections, the Celtics have a 61-percent chance to reach the NBA Finals and a 51-percent chance to win their first championship since 2008. Both teams met in the 2020 East Finals, and Miami won in six games.
