Heat vs Celtics preview – Game 1

Few would deny that the Celtics are the strongest of the four teams left in the 2023 NBA Playoffs, but in order to earn the right to play for what would be an outright record 18th NBA Championship title, they're going to have to go through hell.

The Heat took down the Eastern Conference's top seed, Milwaukee, and have become masters at grinding down hotly-tipped opponents. Plus, in Jimmy Butler, they have one of the most clutch playoff stars of all time – and after that missed buzzer-beater against the Celtics at the same stage a year ago, he's got unfinished business to attend to.

Giving Jimmy Buckets the go-ahead to do his thing might not be the worst course of action that Erik Spoelstra could take, with Jayson Tatum in the form he's in. The Celtics star racked up 51 points in the decider against Philadelphia on Sunday, a record-breaking total for an NBA playoff decider.

Considering the way Jalen Brunson danced through the Heat defense on Friday, Miami can't bank on stopping Tatum. Their best form of defense may be all-out offense, but in order for that approach to work, Bam Adebayo and Duncan Robinson are going to have to be at the top of their games.

Here's how to watch a Heat vs Celtics live stream no matter where you are. Tip-off for Game 1 is at 8.30pm ET / 4.30pm PT on Wednesday.
