Zarren was already in the running for the 76ers' general manager position before withdrawing from consideration; the job went to Sam Hinkie. Zarren has spent his entire life as a Boston Celtics fan and the entirety of his career with the Celtics, for whom he is assistant GM. His love for Boston might be the only thing keeping him from being GM of his own team. Zarren is incredibly respected around the league and known for being one of the forward-thinking and analytics-based minds, bringing praise from the likes of Hinkie and Daryl Morey.
