Another of the original 4 ring of famers; Austin "Goose" Gonsoulin was an outstanding defensive back for the Broncos since their inaugural season through the 1966 season.
From the Broncos official website:
Austin "Goose" Gonsoulin was one of the four original Ring of Fame inductees in 1984, recognized for his splendid play at safety for seven seasons. Gonsoulin was one of the original Broncos from the 1960 season. At the end of his Bronco career, he was the all-time American Football League leader in interceptions with 43. His 11 pickoffs in 1960 are still a Denver club record, and he shares the team record for interceptions in a game with four, a feat he accomplished Sept. 18, 1960 at Buffalo. Gonsoulin was an All-AFL choice in 1960, 1962 and 1963. His amazing durability and toughness enabled him to start 61 consecutive games at one point in his career. Gonsoulin was also the captain of his college team at Baylor. Goose was originally a 17th round selection of the San Fransico 49ers.
