Any list of top defensive lineman would not be complete without Jim Corrigal. The native of Barrie, Ontario went to Kent State and then joined the Toronto Argonauts in 1970 where he would play 12 seasons until 1981. No defensive tackle stats were kept during those years and quarterback sacks ewre only kept in his final season in 1981 when he recorded 4 in just 9 games. If you can't use stats to measure Corrigall's greatness, you can look at his awards. Corrigal won 8 East Division All-Stars (1971, 1972, 1973, 1975, 1977, 1978, 1979 and 1980) and 4 CFL All-Stars (1971, 1973, 1975 and 1977). Corrigal was named the Outstanding Defensive Player in both the East and the CFL in 1981. Corrigial made it to one Grey Cup, which unfortunately for him was the infamous 1971 loss generally blamed on the late Leon McQuay fumble. Jim Corrigal was named to the Canadian Football Hall of Fame in 1990.
Quarterback sack stats were first officially kept in 1981
