Larry Costello

Lawrence Ronald Costello (July 2, 1931 – December 13, 2001) was an American professional basketball player and coach. He played for the Philadelphia Warriors and the Syracuse Nationals / Philadelphia 76ers of the NBA, and the Wilkes-Barre Barons of the EPBL. He served as head coach of the Milwaukee Bucks and the Chicago Bulls. A six-time All-Star, Costello was one of the National Basketball Association's last two-handed set shooters. As the inaugural coach of the Bucks, he led them to a championship in their third season of existence in 1971, the fastest run for an expansion team in NBA history. In ten seasons as a coach, Costello reached the postseason six times, while winning 37 of his 60 postseason games as coach, for a winning percentage of 61.7%, tenth best in NBA history (through the 2024–2025 season). In 2022, Costello was inducted into the Naismith Basketball Hall of Fame as a contributor.
