Cam Jordan and Demario Davis are arguably the best in the league at DE and LB. That leaves starting jobs for one DE and one LB.
DE
Marcus Davenport
Trey Hendrickson
Carl Granderson
Noah Spence
LB
Alex Anzalone
Kiko Alonso
Zack Baun
Kaden Elliss
Anzalone < Davenport
Alonso > Hendrickson
Baun > Granderson
Elliss > Spence
Since pass rush is so important, I'm gonna have to go with DE as the bigger need. Especially one like Griffen.
