Boston Celtics

Win Probability
The Boston Celtics host a Chicago Bulls side that arrives in significantly worse form, and the simulation favours Boston decisively. Jayson Tatum carries a 50% chance of exceeding 39 combined points, rebounds and assists, while Josh Giddey has a 47% chance to surpass 25—a gap that encapsulates the matchup. The game turns on whether Chicago can generate enough scoring depth; Leonard Miller and Caleb Wilson are each at 48% to beat 21 and 25 respectively, but neither approaches Tatum's offensive load. AccuScore's model has won 80% of the time on games shaped this way across 820 prior matchups. For the Bulls to escape, multiple secondary scorers would need to hit their marks simultaneously rather than relying on isolated performances.
