For the Celtics, the past few months have been fairly depressing, though predictable. The team has used this offseason not as a way to vault back into championship contention in 2025-26, but rather to undo the title team it put forth in 2024.

The Boston Celtics and coach Joe Mazzulla have agreed to a multi-year contract extension, the team announced on Friday. Mazzulla enters his fourth year on the job as he looks for a second NBA title after leading the Celtics to their 18th franchise championship in 2024.

Mazzulla, who led the Celtics to their 18th championship a year ago, was entering the final year of his contract with the team.
