Chapter IX: We're the Celtics

Following the 2008 title, injuries, age, and internal conflict take their toll. Though the Celtics return to the Finals in 2010, Danny Ainge quickly pivots to a new era. Soon, rising stars Jaylen Brown and Jayson Tatum are tasked with carrying the weight of the franchise’s storied tradition and the city’s complex racial history. In 2024, under Ainge’s replacement Brad Stevens and head coach Joe Mazzulla, the team captures its record-breaking 18th championship, embodying the legacy of Red Auerbach and Bill Russell as one of the greatest dynasties in sports history.
