Watch Boston Celtics vs Miami Heat — NBA Playoffs R1 G6 Free.

What's at Stake

The Boston Celtics enter the Kaseya Center with a chance to eliminate their fiercest rivals and advance to the next round of the Eastern Conference playoffs. For the Miami Heat, this is a definitive must-win scenario where a loss ends their season, while a victory would force a high-stakes Game 7 back in Boston. This matchup adds another chapter to one of the NBA's most consistent postseason rivalries, with a spot in the semifinals hanging in the balance.

Head-to-Head

These two franchises have become perennial playoff opponents, frequently meeting in the Eastern Conference Finals and early rounds over the last several years. While Boston has held the advantage in the regular season series, Miami has historically proven to be a difficult out in elimination games on their home floor. Momentum currently sits with the Celtics following their Game 5 performance, but the Heat have a reputation for extending series when their backs are against the wall.

Key Players to Watch

• Jayson Tatum — The Celtics forward will look to lead the scoring charge and close out the series to avoid a stressful return to Boston.
• Jimmy Butler — Known for his postseason heroics, the Heat veteran must deliver an elite two-way performance to keep Miami's season alive.
• Jaylen Brown — His ability to attack the rim and provide secondary playmaking will be vital in breaking down Miami's disciplined zone defense.

Prediction

Expect an incredibly physical and low-scoring affair as Miami relies on their defensive grit to slow down Boston's high-powered offense. While the Heat are likely to keep the game close until the final minutes, the Celtics' depth and perimeter shooting should ultimately allow them to pull away. Boston is predicted to win a tight contest, securing the series 4-2 and ending Miami's postseason run.
