One of the fiercest players in NFL history, Butkus was the Bears' middle linebacker from 1965-73. The Hall of Famer's No. 51 was retired. Butkus made eight Pro Bowls and was a six-time first-team All-Pro. The two-time defensive player of the year was voted onto the all-decade teams for the '60s and '70s.
