Boston's 2025-26 season ended in the first round of the playoffs. The Celtics led Philadelphia 3-1 before the 76ers won three straight to take the series 4-3, closing it out in Game 7. With a new season on the horizon, bettors will be watching the Boston Celtics odds as Boston begins its title campaign.
