March 24 vs Cleveland Cavaliers (and March 20 at Cleveland)
It’s unlikely the Heat will be able to catch the Cavaliers in the standings but these games will still be important.
The Cavs have the East’s second-best record and are arguably the hottest team in the league since the turn of the calendar. Wins against them would be among the biggest statements the Heat could make.
There’s also the chance that this is a first-round preview. If the Heat end up with the sixth or seventh seed in the East, there’s a chance they could end up facing the Cavs in a first-round series.
