| Rest | −40 | — | BOS on the second night of a back-to-back |
| Lineups | −11 | +37 | BOS: Weaker than its recent lineups · GS: Missing Jimmy Butler III −44, Kristaps Porzingis −31, Brandon Williams −4 · otherwise stronger than recent lineups (from the injury report) |

| Market-implied ratings | BOS 53.9% | Team strength as past closing lines priced it, same game context | |

Tale of the tape
This season coming into the game, regular season, each number with its league rank (the longer the bar, the higher). Home and road: the host's record at home against the visitor's on the road. Opponent Elo: how strong the teams each has played are, 1st the toughest. Adjusted: the scoring model’s ratings a game, which account for who they played. Offense and defense are points per 100 possessions, which sets aside how fast a team plays.
