Isaacs’ biggest contributions came well after his playing days ended. For decades, he mentored youth in the South Bronx at the Madison Square Boys and Girls Club, the kids not aware at all (usually, until they saw him on TV) that the still-fit elderly man was a trailblazer and a vocal critic of the conditions he and his teammates had to endure, on and off the court. Future NBA legends like Tiny Archibald came through the Madison Square Club as kids, shaped by Isaacs’ big voice and reservoir of stories.
