- Mike Vorkunov of The Athletic takes a look at how Bill Chisholm went from relative obscurity as a wealthy head of a private equity firm to the new majority of the Celtics, the team he grew up rooting for as a child. While Chisholm’s group set a then-record for purchasing the Celtics for $6.1 billion, they outbid the second-place finisher — believed to be Philadelphia Phillies minority owner Stan Middleman — by less than $100MM, sources tell Vorkunov. “Anyone who’s had their boyhood team or girlhood team and have this happen — I want to say it’s like a dream come true but… I didn’t even know to dream this,” Chisholm said. “What does it mean to be the owner of the Boston Celtics? I don’t know.”
