Chiefs’ top 10 sack leaders have changed thanks to addition of pre-1982 sacks

3 members of the Super Bowl IV team are now among the #Chiefs’ sack leaders with Pro Football Reference’s addition of pre-1982 sacks.

The Kansas City Chiefs have a new unofficial list of sack leaders thanks to the folks over at Pro Football Reference.

The sack didn’t become an official NFL stat until the 1982 season and the league has only officially counted sacks from that point onward. The current leaderboards of sack leaders that you’ve probably seen for the Chiefs on Pro Football Reference and elsewhere have been incomplete. That is, of course, until now.

The folks at PFR have worked tirelessly to compile sacks between 1960 and 1981. They’ve created a new unofficial leaderboard for the NFL career leaders, single-season leaders and leaders of individual teams. A few things have changed for the Chiefs’ career leaders because of the addition of pre-1982 sacks. Namely, some of the great pass-rushers from the earliest moments in franchise history have moved up to take their rightful place in the leaderboards.

Below you can find a look at both the official totals and unofficial totals for the top 10 career leaders for the Chiefs via PFR:
