A scrappy player who played on the strong St. John's teams of the earl 1950's, Jack McMahon was drafted by the Rochester Royals of the NBA. The 6'1 guard would play three full season with the Royals and was halfway through his fourth when he was traded to the St. Louis Hawks. In his second full season with the Hawks, he was a key part of the team as they won the NBA championship. He would finish his 8-year NBA career with the Hawks, and continue in the game as a coach, scout and administrator.
McMahon was hired to coach the Kansas City Steers in the fledgling American Basketball League in 1961. After the season, he was hired to coach the Chicago Zephyrs in the NBA. He unfortunately only lasted half-way into the 1962-63 season, being fired in December of 1962 after a 12-26 start. He was not out of coaching for long, as in June of 1963, the 33-year old McMahon was hired to lead the Cincinnati Royals, the team who drafted him when they resided in Rochester. He coached the Royals for fours seasons, making the playoffs each year, before leaving the club in 1967 to become the head coach and general manager for the expansion San Diego Rockets.
After a rough inaugural season (which is normal for first-year teams), the Rockets improved in McMahon's second year at the helm and made the playoffs, losing to the Hawks in 6 games. A slow start in 1969 lead to another December dismissal for McMahon, and the next two seasons would see him lead the Pittsburgh Condors in the ABA. He was hired by the 76ers in 1972 as the director of player development, and eventually became an assistant coach as well. In his decade-plus with the Sixers, McMahon played a key part in scouting and developing the players that lead to many great teams. In 1986, he parted ways with Philadelphia to join the Golden State Warriors. In June of 1989,
he was attending a pre-draft camp in Chicago in order to scout for the Warriors. He fell asleep in his hotel room while reading a book one night, and never awoke. He was 60 years old.
Jack and his wife, Katherine, had three children.
