Sacks are an overrated stat.
Most guys face one opponent OL blocking them and "all" they have to do is get by that one guy.
To compare AD's sack totals to other guys that rarely faced 2B or 3B teams is silly.
Nobody was ever 2B and 3B teamed like AD.
Other Ram defenders benefitted in sack totals and contract $ signed because AD did the dirty work for them.
Greatest player I ever saw.
