Fans and analysts are calling for Joe Mazzulla’s firing after the Celtics’ historic collapse in the playoffs. On May 3, 2026, the Boston Celtics lost Game 7 against the Philadelphia 76ers, marking a significant turning point for the franchise. The defeat was particularly shocking as it was the first time in history that the Celtics lost a series after leading 3-1.
Before this debacle, expectations were high. The Celtics entered the playoffs as the No. 2 seed in the Eastern Conference and had aspirations of capturing another NBA Championship. Jayson Tatum, a key player for Boston, was sidelined with an injury during Game 7, but many believed they could still overcome their opponents.
That context matters because it highlights how unexpected this collapse was. The final score—109-100 in favor of the 76ers—wasn’t just a loss; it represented a failure to capitalize on their earlier success. In Game 7, three starters for the Celtics shockingly scored zero points, setting a playoff history first.
The fallout from this game has been severe. Fans immediately took to social media, expressing their outrage and calling for Mazzulla’s dismissal. Comments like “If Mazzulla isn’t fired by midnight, we riot” reflect a growing sentiment that change is necessary. Analysts have also criticized Mazzulla’s rotation decisions throughout the series, suggesting that his coaching strategies contributed to this monumental failure.
Experts weigh in on what went wrong. Joe Mazzulla himself expressed feeling empty after the loss—a stark contrast to his emotions following their previous championship victory. His duality of experience—having led the team to an NBA Title yet now facing potential firing—illustrates just how quickly fortunes can change in sports.
The immediate effects on Mazzulla’s career remain uncertain. Will he keep his job? Or will management decide that a different approach is needed to lead this talented roster? As discussions continue, one thing is clear: this loss will linger in Boston’s sports history.
