Twogood returned to USC as an assistant basketball coach under Barry in 1949,[3] and when Barry died of a heart attack in September 1950, Twogood was promoted to head coach,[8] and served for 16 seasons. In 22 seasons as a head coach, he compiled a 317–260 (.549) record, with two conference championships and three NCAA tournament appearances, including the Final Four in 1954. After stepping down from coaching in 1966, Twogood was an assistant athletic director at USC. The auditorium at the university's Heritage Hall is named in his honor;[9][10] its bronze plaque reads:
"Athlete and coach, able administrator, dedicated sportsman, man of courage, honor and compassion, Forrest Twogood is synonymous with the athletic heritage of the University of Southern California. He served USC and intercollegiate athletics with brilliance and devotion. The university is proud to express its love and esteem for Twogie by designating this hall forever in his name."[9]
Diagnosed with inoperable lymph gland cancer in late 1971, Twogood died in April 1972 at Glendale Memorial Hospital in the Los Angeles suburb of Glendale, a few days shy of his 65th birthday. He left behind his beloved wife Eleanor, sisters Blanche and Lucille, and several nieces and nephews Dick Evans and David Stockman, US Naval Academy 1951 Col (Ret) USAF and fighter pilot, and wife Lucia, as well as David and Lucia's children Sidne Ann and Bill Stockman, who loved him dearly [11]
