Boston ISA Fuels Fan Culture for New NWSL Franchise

On March 14, 2026, the Boston Independent Supporters’ Association (ISA) marched into Gillette Stadium for the Boston Legacy’s inaugural match. Members unfurled a “Our Legacy Takes Flight” tifo, filled the supporters’ section behind the north goal, and energized the crowd of over 30,000 with drums, chants, and flags. Their presence has been a constant at every home game, regardless of weather, venue, or result.

Boston’s last professional women’s team, the Breakers, folded after the 2017 season, leaving a decade-long gap for local fans. The NWSL announced Boston as an expansion city for the 2026 season in September 2023, prompting the ISA’s formation shortly thereafter. The Legacy has lacked a permanent home, splitting matches between Gillette Stadium in Foxborough and Centreville Bank Stadium in Pawtucket while White Stadium in Boston remains under construction until 2028. Early branding missteps—initially naming the club “BOS Nation FC” with the “Too Many Balls” tagline—were revised after fan backlash, with the ISA contributing feedback through focus groups.

ISA membership chair Anna Esten emphasizes the group’s financial independence and strategic role in shaping fan experience. Former Legacy community marketing manager Jammy Torres Millet notes the ISA’s early liaison work with club founders. Executive director of the NWSL Players Association Meghann Burke highlights supporters as “key partners” that extend beyond match-day atmosphere to broader player-rights advocacy. Goalkeeper Casey Murphy and defender Bianca St-Georges have publicly embraced the team’s aggressive identity, encouraging opponents to “hate” playing in Boston.
