Head-to-Head

Boston and Miami have developed one of the most intense rivalries in modern basketball, frequently meeting in deep playoff runs. While the Celtics have held the edge in recent regular-season encounters and secured the higher seed, the Heat have historically thrived as underdogs in this matchup, often pushing series to the limit with their physical defensive style. Momentum favors the home side, but the psychological history between these two rosters remains a significant factor.

Key Players to Watch

Expect a physical contest where the Celtics prevail 112-102.
