By the start of the 2013 season, none of the "Big Three" were still with the team, which ushered in a new era for the team. With the help of newly hired head coach Brad Stevens, the team began rebuilding. In his second season, Stevens led the Celtics on a return to the playoffs in 2015. During the 2016-17 season, the Celtics clinched the top seed in the Eastern Conference, but were eliminated in the Conference Finals. Led by Jayson Tatum and Jaylen Brown, the team returned to the Conference Finals in 2018 and 2020, losing both times.
