round two years in a row. In 1964, Hannum was named NBA Coach of the Year while with the San Francisco Warriors after leading them to the Finals against the Celtics. In 1966, Hannum was named the head coach of the Philadelphia 76ers. That team had moved from Syracuse three years earlier. He succeeded Dolph Schayes, who had been named coach after the move from Central New York. During his first season as coach, the 76ers had a record setting season as they started 46–4, en route to a record of 68–13, the best record in league history at the time. After a 129–103 win over the Pistons on March 3, 1967, he joined Red Auerbach as the only coaches to have won 60 games in a season at that period. Hannum led the Sixers towards the 63rd victory, breaking the NBA-record for most wins in a single season, in an OT win over the Boston Celtics. On March 14, 1967, he became the first coach to have won 65 games in a season. Hannum then coached the Wilt Chamberlain-led Philadelphia 76ers to the NBA championship, ending the eight-year title streak of the Boston Celtics. The 1967 Championship made him the first of only three head coaches in NBA history to win championships with two different teams (the other two are Phil Jackson and Pat Riley). In 1968 Hannum was named head coach and executive vice president of the Oakland Oaks of the American Basketball Association. Hannum coached the Rick Barry-led Oaks to the 1969 ABA Championship, becoming the first of two coaches to win championships in both the NBA and ABA. Hannum won the ABA Coach of the Year honors the same season. Hannum left his position as head coach of the San Diego Rockets of the NBA to become president, general manager and head coach of the ABA's Denver Rockets on April 8, 1971. In his first season the Rockets lost their opening playoff match to the Texas Chaparrals. On June 13, 1972, Hannum bought control of the Rockets with A.G. "Bud" Fischer and Frank M. Goldberg. In the 1972–73 season Hannum coached the Rockets to the 1973 ABA Playoffs where they lost in the first round of the Western Division playoffs to the Indiana Pacers, 4 games to 1. Hannum returned the Rockets to the 1974 ABA Playoffs where they lost to the San Diego Conquistadors. On
