McD/Frazier's Bills have never finished top ten in sacks as a team and never produced a single double digit sack player to this point.
Again, "mediocre" is probably a better word there. Anecdotally, they disappointed in key situations, like in several playoff exits.
The #1 and #2 teams in the NFL in sacks last year were the Chiefs and the Eagles. I'm encouraged by the change I'm seeing this year 🤷♂️
