Kevin Greene
Greene has the most sacks out of anyone’s NFL career (160) in history, in addition to being the oldest player to ever lead the league in sacks, with 14.5 sacks in 1996 at the age of 34. Kevin Greene was indicated to the Hall of Fame in 2016 with five Pro Bowls under his belt, as well as three All-Pro nominations. Greene hung up his jersey in 1999 after a 15 year-long career in the big leagues.
Cornelius Bennett
Bennett was insanely explosive on the field. So much so, that he suffered several injuries while playing, which he pushed through and only told personnel about after the plays were made. In fact, Bennett had 1,190 tackles, 71.5 sacks, seven interceptions, and 31 forced fumbles over the course of only 206 games, if his methods were sustainable, he might have been, statistically, the greatest linebacker of all time. However, longevity is a leading trait for the greatest football players, which Bennett did not exhibit.
