Team	Probability
Boston Celtics	71.8%
Philadelphia 76ers	28.2%

When digging into the stats of the first two games of the series, we put a lot of stock in underlying efficiency, and the Celtics establish themselves as the clear frontrunners. Boston boasts a dominant 8.8 Net Rating despite losing Game 2. The Celtics also control the glass much more effectively, grabbing 53.1% of available rebounds.

It does stand to reason that Boston enters this matchup as the heavy favorite with a 71.8% implied probability. However, situational context matters. While Boston dominated Game 1, 76ers coach Nick Nurse adjusted his lineup by bringing in Andre Drummond, and rookie V.J. Edgecombe just dropped a historic 30-point, 10-rebound performance in Game 2 alongside Tyrese Maxey’s 29 points. Boston’s Joe Mazzulla is focusing heavily on pick-and-roll defense to counter Philly’s guards, but until Joel Embiid returns from his emergency appendectomy, Boston’s massive statistical edge on the boards remains a defining factor.
