For much of the 1980s and 1990s, Kloppenburg was an NBA assistant coach with the Cleveland Cavaliers, Seattle SuperSonics, Denver Nuggets, and Toronto Raptors; he also had brief stints as interim head coach for the Cavaliers and SuperSonics.

Coaching career

Early coaching career (1951–1958) In the 1951–52 season, Kloppenburg was junior varsity coach for Fresno State. The following season, Kloppenburg was head coach at Lindsay High School at Lindsay, California. At Lindsay, Kloppenburg emphasized defense and ball control in a coaching style inspired by Hank Iba and Pete Newell. Kloppenburg returned to Southern California to be head coach at Victor Valley High School in Victorville, California beginning in 1953–54. In 1956, Kloppenburg became head coach at Paramount High School in Paramount, California. Although Paramount had a strong interior defense, Kloppenburg adapted his defensive coaching to compete against teams like Compton High School that specialized in jump shooting. In 19 seasons at California Western/U.S. International, Kloppenburg had a cumulative 322–192 record from 1958 to 1978 with NAIA tournament appearances in 1963, 1965, 1966, and 1975. Kloppenburg led Donar to a 19–17 record. After one final season at U.S. International in 1977–78, in which the team went 12–15, Kloppenburg left for the second and final time due to what he believed were inferior facilities that affected recruiting. On December 3, 1981, Kloppenburg became interim head coach for the Cavaliers after the firing of head coach Don Delaney. Kloppenburg went 0–3 as interim coach before Chuck Daly formally took over. The team finished the season 15–67 under four different head coaches.

After leaving the Cavaliers, Kloppenburg was a scout for the San Diego Clippers in 1982–83 and Washington Bullets in 1983–84. In 1984–85, Kloppenburg was an assistant coach at UNLV under Jerry Tarkanian. UNLV went 28–4 and qualified for the second round of the NCAA tournament.

After UNLV, Kloppenburg returned to the NBA for a second stint as assistant coach for the SuperSonics that lasted from 1985 to 1995 under head coaches Bernie Bickerstaff, K. C. Jones, and George Karl.

Prior to the 1995–96 season, Kloppenburg reunited with Bickerstaff as an assistant coach for the Denver Nuggets for one season. Kloppenburg's final coaching job was with the Toronto Raptors in 1997–98.

Coaching style Kloppenburg is regarded as the innovator of the SOS defensive system, known for its ability to create turnovers because of "contact switching" on every screen and intense ball pressure with trapping principles. He is married to Gayle Kloppenburg.

Kloppenburg died on April 16, 2024, at the age of 96.
