Here are the 1971 Chicago Bears. The Bears just came off a 3rd-place, 6-8 season, and repeated that in 1971. The only bright spot here is that Gale Sayers and Dick Butkus would eventually make the Fall of Fame.
Gale famously injured his knee in the 9th game of the 1968 season, and missed the remaining 5 games. His other knee was injured in 1970, causing him to miss 12 games in 1970 and 12 games in 1971. Sayers retired after the 1972 pre-season, and was inducted into the Hall of Fame in 1977.
