John Tracey was taken in the Fourth Round by the Chicago Cardinals in 1959, and while the former Texas A&M was active for the Cards in his first two seasons (and a third with the Philadelphia Eagles), he was not a star by any means, and he was essentially castoff. Luckily for Tracey, the American Football League made a nice landing spot for the Linebacker, and he signed with the Buffalo Bills in 1962.
Along with Mike Stratton and Henry Jacobs, Tracey was part of a fast and athletic Bills Linebacking corps. The Bills defense was the key side of the ball that took Buffalo to an AFL Championship win in 1964 and 1965, and he was also an AFL All-Star twice (1965 & 1966).
Tracey retired after the 1967 season, and he would have 11 Interceptions for Buffalo.
