Story byAdam Taylor, Celtics WireMon, December 29, 2025 at 2:46 PM UTC·1 min readWith a 19-11 record to begin the new NBA season, the Boston Celtics are proving that they're still one of the best teams in the Eastern Conference, despite a significant amount of turnover this summer. After Jayson Tatum suffered an Achilles tendon injury during the Eastern Conference Semifinals against the New York Knicks, Brad Stevens embarked on a cost-cutting mission, parting ways with four key members of the rotation. However, Joe Mazzulla's coaching methods are paying dividends with a young and hungry Celtics roster. Led by Jaylen Brown, who is playing at an All-NBA level, Boston sits third in the East and could potentially cement itself as a true force if Tatum is cleared to return at some point during the season.
