Five Reasons Celtics Fans Should Cheer for the Spurs in the NBA Finals

As June rolls in, Boston Celtics supporters find themselves sidelined after a first-round exit from the 2026 NBA Playoffs at the hands of the Philadelphia 76ers. With no games to watch, they must now sit back and observe the upcoming NBA Finals, featuring the San Antonio Spurs and the New York Knicks. While neutral fans can enjoy the matchup, Celtics fans might want to consider rooting for the Spurs. Here are five compelling reasons to do just that.

One of the standout players for the Spurs is Luke Kornet, a name that has become synonymous with Boston pride. Kornet joined the Celtics in 2022, and during his time there, the team reached three Eastern Conference Finals and two NBA Finals, ultimately claiming the championship in 2024. Although he was not the key player driving those victories, his presence in the locker room and steady performance off the bench earned him a special place in the hearts of fans. After departing for a four-year, $41 million contract with the Spurs, Boston fans can take pride in cheering him on as he pursues another championship.

Another familiar face on the Spurs is Kelly Olynyk, who has a memorable history in Boston. Olynyk captured the attention of fans during a thrilling Game 7 in the 2017 Eastern Conference Semifinals, where he scored a staggering 26 points against the Washington Wizards. Despite the Celtics falling short in the following round, Olynyk's performance solidified his status as a local legend. Now that he has joined the Spurs, Celtics fans can find themselves rooting for the player who once delivered such a memorable playoff moment.

The connection between the Celtics and Spurs runs even deeper through family ties. Spurs rookie Dylan Harper has been a sensation this postseason, and he is the younger brother of Celtics guard Ron Harper Jr. The elder Harper has openly celebrated his brother's achievements throughout the playoffs, adding a personal stake for some Celtics players as they watch the Finals unfold.

Additionally, Celtics guard Derrick White has a unique reason to support the Spurs, as he was traded from San Antonio to Boston in February 2022. White has shared how legendary Spurs coach Gregg Popovich ensured he landed in a good organization, making the Celtics an ideal fit. His arrival led to a successful stint in Boston, culminating in a championship run, and White remains a vital contributor to the team's success.

Finally, for any Celtics fans uncertain about who to support, the historical rivalry between Boston and New York might sway their decision. The Celtics and Knicks have a long-standing animosity, while the Spurs are a much less contentious opponent, historically speaking. With the Celtics and Spurs rarely crossing paths, Boston fans can root for San Antonio without the baggage of rivalry.
