Davis played in an era when neither tackles nor sacks were official statistics. However, John Turney, a member of the Professional Football Researchers Association, reports that Davis had in excess of 100 sacks during his 10-year Green Bay career, "possibly more than 120," including a minimum of 40 over the 1963–65 seasons alone. Davis himself is quoted as saying, "I would think I would have to be the team's all-time leader in sacks. I played 10 years and I averaged in the 'teens' in sacks for those 10 years. I had 25 one season. Paul Hornung just reminded me of that the other day." Davis earned All-Pro honors 5 times and was voted to the Pro Bowl five times. He was inducted into the Pro Football Hall of Fame in 1981.
