John Phillip Bengtson (July 17, 1913 – December 18, 1994) was a college football player and longtime assistant coach on the collegiate and NFL levels, chiefly remembered as the successor to Vince Lombardi as head coach of the Green Bay Packers in 1968.
Bengtson took his first assistant coaching job at the Missouri in 1935, but soon returned to his alma mater as line coach, staying through the 1939 season. Beginning in 1940, he moved to Stanford, where he served as an assistant coach for twelve years. Bengtson moved to the professional level in 1952 with the nearby San Francisco 49ers.
In seven seasons with the Niners, Bengtson would serve under three head coaches: (Buck Shaw, Red Strader, Frankie Albert) before being dismissed with Albert after the 1958 season. Soon after, he was one of the first four assistants hired in Lombardi's first week with the Packers in early February 1959.
Phil Bengtson would be the only assistant coach to stay during the entire nine-year tenure of Lombardi (1959-1967). His work as defensive coordinator of the Packers established his coaching ability and put him in line to succeed Lombardi. From 1961-67, the Packers captured five NFL titles, and the first two Super Bowls.
Bengtson replaced Lombardi following the 1967 season; his low-key approach was in sharp contrast to the often-volatile Lombardi. With the aging of key players, this translated into mediocrity for the franchise. Bengtson's Packers were 20-21-1 in his three seasons as head coach. After a 6-8 record in 1970, he was relieved of his duties, replaced by Missouri head coach Dan Devine for the 1971 season. Devine lasted four seasons with the Packers, moving back to the collegiate level at Notre Dame following the 1974 season. Lombardi's former quarterback, Bart Starr, became the head coach of the Packers in 1975.
