Gregg became a nine-time Pro Bowl and All-Pro selection during his career in Green Bay. He guided the Bengals to their first Super Bowl during the 1981 season. Gregg spent most of his career playing right tackle, but also offered to play guard whenever Lombardi needed a fill-in.
But fans of the Cincinnati Bengals might remember Gregg just as fondly as the Packers.
Gregg played for the Packers in 1956 and from 1958-1970. Almost 40 years after that Super Bowl berth, the Bengals honored him with a banner at Paul Brown Stadium in 2017. We had good people, good players and he got the best out of them. They went out and did what they had to do, and what we were doing worked. Gregg left after the 1987 season to coach his alma mater, SMU.
