Michael Ray Richardson, a four-time NBA All-Star and renowned for his defensive skills during his career with the New York Knicks, Golden State Warriors, and New Jersey Nets, has died at age 70. His death followed a diagnosis of prostate cancer, as confirmed by his friend and attorney John Zelbst. Richardson, nicknamed 'Sugar,' was the NBA's 1985 Comeback Player of the Year and averaged 14.8 points, 7.0 assists, 5.5 rebounds, and 2.6 steals per game over his eight-year career. Despite his impressive stats and impact on the court, his career was marred by a lifetime ban in 1986 due to multiple violations of the league's drug policy, primarily related to cocaine addiction, which he openly discussed in interviews and wrote about in his autobiography, 'Banned: How I Squandered An All-Star NBA Career Before Finding My Redemption.' Richardson continued his basketball career in Europe after his ban and is regarded by many as one of the greatest players never inducted into the Hall of Fame. His legacy is characterized by his exceptional talent and his struggles with addiction and redemption.
