Wyc Grousbeck, co-owner of the Boston Celtics, announced the team's sale despite recent success and an NBA championship. Grousbeck clarified that he does not own the majority stake in the franchise and revealed plans for a two-part sale, with 51% expected to be sold soon and the remaining 49% in 2028. His co-owner, Steve Pagliuca, expressed interest in the bidding process. The sale is driven by estate and family planning considerations, with Grousbeck intending to stay until 2028. The team, including players like Jayson Tatum, is preparing for the upcoming season amidst the ownership transition.
