Celtics’ Collapse: Bill Simmons Blames Coach Joe Mazzulla
The Boston Celtics’ shocking first-round exit has sparked intense debate, with renowned sports journalist Bill Simmons pointing the finger at head coach Joe Mazzulla. Despite voting for Mazzulla as Coach of the Year, Simmons is baffled by the team’s collapse against the Philadelphia 76ers.
According to Simmons, Mazzulla’s decision to abandon the team’s fast-paced, deep-rotation identity and instead experiment with a new approach was a catastrophic mistake. “They went back to their 2024 style without the same players,” Simmons lamented. “They slowed it down. They didn’t put up pace. They gave up on their bench.” This move not only stymied the team’s momentum but also left energetic role players like Hugo and Walsh on the sidelines.
Simmons also criticized Mazzulla’s handling of star player Jayson Tatum, who was pushed too hard after recovering from a ruptured Achilles. Tatum logged 39, 42, 35, and 41 minutes between Games 2 and 5, which ultimately led to a lower leg injury in Game 6 and his absence in the decisive Game 7.
The consequences of Mazzulla’s decisions were drastic. Without Tatum, the replacement starting five, consisting of Luka Garza, Baylor Scheierman, and Ron Harper Jr., made history for all the wrong reasons, combining for zero points in Game 7. This feat marked the first time since the 1970-71 season that a starting trio had gone scoreless in a playoff game.
Ultimately, Simmons believes that the Celtics’ collapse was a self-inflicted wound. While the 76ers won the series, Simmons argues that Boston “completely blew it.” As the team reflects on what went wrong, fingers will undoubtedly be pointed at Mazzulla’s coaching decisions. Will the Celtics be able to rebound from this disappointment, or will the ghosts of this collapse haunt them for years to come?
