Four times an All-Star with the Atlanta Hawks, Al Horford signed with the Boston Celtics in 2016 with the hope that this would be the team that would earn him his first NBA Championship.  It finally happened in 2024.

In Horford’s first season in Boston, he averaged 14 Points per Game.  He was a solid defensive player, helping the Celtics push Cleveland to a seventh game in the Eastern Conference Finals.  The year after, Horford added his fifth All-Star selection, won Second Team All-Defensive honors, and helped lead his team to the ECF, where they lost to the Cavaliers.  After another solid season in 2018-19, where he averaged 12.6 Points and had a career-best .586 in Effective Shooting Percentage, Horford signed with division rival Philadelphia, but that did not end his story in Boston.

The Celtics reacquired Horford, who was now with Oklahoma City, in a trade before the 2021/22 Season, and though the Center was aging, he was still a valuable starter capable of big moments.  Horford and the Celtics reached the 2022 Finals, and though he dipped below 10 Points per Game for the first time in 2022/23, his leadership still helped the Celtics make another deep playoff run.

In 2023-24, Horford started in only half of his games, but even with a reduced role, his veteran presence and defensive skills helped Jayson Tatum and Jaylen Brown win it all, with the trio winning their first NBA Championship.  Horford played one more year with Boston before leaving for Golden State as a Free Agent.
