Looking at the all time NFL records...
for Sacks I noticed that only 4-5 of the names in the top 15 are the ones that you expect: Dent, Smith, White, etc. Most are names that are certainly not ones that you will remember. Or ones that will be in the HOF.
ALSO- if you want to win a cheap bet sometime- ask an "expert" who got more career sacks- Charles Haley or Jim Jeffcoat. Odds are he will pick Haley- and he will be wrong: Haley had 100 career sacks- Jeffcoat had 102.
