No. 2 - Sign edge rusher Dante Fowler, Jr. in free agency
Fowler is a bit of a risk. He could be extremely disruptive as a pass rusher or simply just OK. Either way, the Seahawks will be in need of more proven pass rushers next year. Uchenna Nwosu will be coming back from injury, so that will help. Boye Mafe is definitely been better in his second season. But after those two, there a vast wasteland of proven edge rushers.
Derick Hall might be able to take the same jump that Mafe did in 2024, but Hall hasn't been as good as Mafe was in Mafe's first year. There is no evidence yet that Hall will be a capable player in the NFL. He has good size and strength, but he also has zero sacks and just one tackle for loss in 2023. As a second round pick, he should have been able to do a bit more.
Darrell Taylor will be a restricted free agent for Seattle next year and while Taylor got 6.5 sacks in his first season playing in the NFL and then 9.5 last year, he has greatly digressed in this season. He has 3.5 sacks and 6 quarterback hits in 2023, but no sacks in the last five games and just one QB hit. He is still horrible against the run, too. He likely isn't even worth keeping on the roster even as a restricted free agent.
Fowler had at least 4.5 sacks between 2019 and 2022 with a high of 11.5. He also is only getting paid $3 million this year and doesn't play enough to earn a huge increase next season. He is certainly an upgrade over Taylor and that should make the Seahawks at least a little bit more dangerous in terms of pass rush.
