He played college football for the University of Michigan from 1961 to 1963. He also played 12 seasons of professional football in the American and National Football Leagues from 1964 to 1975. He was an AFL All-Star in 1966 and 1967, a key to the 1967 Oakland Raiders' defensive line that led the team to a 13–1 record and the 1967 AFL Championship, and was considered "the premier tackle in the old American Football League". He was known for his use of a distinctive four-point stance in which he lined up with both hands on the ground.
