In 1999, Davis was ranked number 69 on The Sporting News' list of the 100 Greatest Football Players.
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."
