the sack records

Still irks me that the league doesn't go back to at least the 1970 merger to update true sack numbers. Ideally back to 1960 and the start of the AFL. Just would not be that hard. Sacks starting in 1982 is just so arbitrary and of course inaccurate. I even have old football cards from childhood that include things like Jack Youngblood with 18 sacks in 1979, etc.
