Celtics-Heat live stream: How to watch Game 1 of ECF


The Boston Celtics and Miami Heat will begin their battle for a trip to the NBA Finals on Tuesday night.

After their upset series victories over the Toronto Raptors and Milwaukee Bucks respectively, these two teams are bound to put on a show in the conference finals. It'll undoubtedly be a competitive series with Jayson Tatum, Jaylen Brown, and Kemba Walker on one side and Jimmy Butler, Bam Adebayo, and Goran Dragic on the other.

Boston also will see a couple of old friends in former Celtics Jae Crowder and Kelly Olynyk, who last played for the C's during the 2016-17 campaign.

The Celtics have a 2-1 edge in the regular season series, but the Heat earned the win in their most recent matchup on Aug. 4. If those three meetings are any indication, we're in for a thriller of an Eastern Conference finals.
