A Hall of Fame induction in 1991, Jones played 12 of his 13 NFL seasons with the Bears. He was a fixture at guard for eight seasons before adding defensive tackle duties in 1962, then switching exclusively to DT in 1963. He went to seven straight Pro Bowls from 1955-61 and missed just two games in his first 11 seasons.
