This is an interesting debate. My initial reaction was, no way is the 2023 Seahawks' pass rush comparable to Avril and Bennett! The 2013 defense was historically great. But on closer look, you're right that the 2013 team, as good as it was, was not a sacking machine. The 2013 team was 9th in sacks with 44, while the 2022 team, a team that we can all agree was mediocre or worse, was 9th with 45 sacks.
This probably shows the inadequacy of sacks as a statistic to tell a significant story. Bennett and Avril were two pro-bowl players who were among the best in Seahawks' history. In his best year, Bennett had 10 sacks, 18 TFLs. and 30 QB hits. Avril had 11.5 sacks, 8 TFLs and 26 QB hits.
But Uchenna Nwosu had a great season last year, with 9.5 sacks, 12 TFLs, and 26 QB hits. Granted, he had one extra game to compile those stats, but still a pretty good year. But I don't think that anyone else on the Seahawks had comparable production last year. Yes, Darrell Taylor had 9.5 sacks, but his pressure rate wasn't that great. If Derick Hall can come in and be the player that we expect him to be, that might be a pretty good combo, that might rival the Bennett/Avril tandem. And maybe Boye Mafe can take a big step forward this year. Remember, Frank Clark didn't shine in his first year, either. (Btw, Clark, Avril and Bennett played together for a couple of years, and in 2016, the three of them probably would have each had double digit sacks if Bennett hadn't gotten hurt.)
