The Boston Celtics are set to tip off their new season on Oct. 22 against the Philadelphia 76ers. Earlier today, the Celtics’ new ownership group met with the media. Bill Chisholm, the team’s lead owner and governor, shared his excitement about owning the team, describing it as a “dream come true.” Chisholm, who grew up a diehard Celtics fan, acknowledged that the honeymoon period will be brief.
