Tsai also forced out John Abbamondi, the CEO of Brooklyn Sports Entertainment (BSE), the parent company of the Nets and Barclays Center, who announced in February that he would leave at the end of the season. Tsai is now searching for his third top business executive in under three years. Though the Nets set records for attendance, ticket revenue and sponsorships under Abbamondi, Tsai’s huge investment led him to believe a good showing should have been great. The Taiwan-born billionaire felt Abbamondi was not innovative or data-driven enough, sources close to the situation told The Post.
