The NFL has two sets of sack stats – the official one that dates to 1982 and an unofficial one that dates to 1960.

Sacks became an official NFL statistic in 1982. But based on the work of John Turney and Nick Webster of the Pro Football Researchers Association that was published in 2021, “a very thorough accounting” of pass-rushing has emerged that pushes the sack, at least unofficially, back to the 1960 season.

The 10 players from Alabama high schools and colleges with the most NFL sacks officially would not be quite the same as the 10 using the unofficial tabulations that add 22 seasons to the sack stats.

Former Parker High School star and Pro Football Hall of Fame member Buck Buchanan played his whole career with the Kansas City Chiefs before the sack became an official statistic. The research statistics credit Buchanan with 70.5 sacks for the Chiefs from 1962 through 1975.

That total would rank Buchanan ninth on the Alabama list.

On either list, the player from an Alabama high school or college with the most NFL sacks is Kevin Greene with 160. Officially, that’s the third-most in NFL history and the most for a player whose primary position was linebacker. The unofficial totals move Greene to fourth. In addition to trailing Bruce Smith and Reggie White on the official list, the research stats move him behind Deacon Jones, too. Smith, White and Jones played defensive end.

During the 2022 NFL season, the player with Alabama football roots with the most sacks was New York Jets defensive tackle Quinnen Williams (Wenonah, Alabama) with 12.
