I know because the Dallas Cowboys front office kept those records even if the NFL didn’t officially. Even ESPN stated in a 2015 article that the Cowboys credit Pugh with leading the team in five straight seasons, topped by racking up 15.5 in 1968, and that he averaged 12.5 sacks over five seasons.
I saw Jethro Pugh play in person 4 times when I was a kid. He was a great player. Remember the rules were different back then and DL could use their hands differently than today.
which means just about any and every other NFL team could have a chosen player of their own
that want to have their own club record of 12-13 sacks a game as well.
Sounds like an exaggeration as If Pugh was getting 12 sacks a game, he would have
been an Hall of Famer in the same sense as Lilly.
i've heard past posters suggest " broadcasters " were giving such sack stats out as well.
Sad that NFL waited so damn long to finally start recording NFL sacks (which players use as contract leverage to this very day) as even more confusing as why NFL could not get their own official statisicians
to gather every recorded game on film since beginning of time in NFL history. But who knows how
full recorded or quality preserved those film games were.
