Personally I dont think Fuller has been bad this year. Somewhat less than 2020? Sure. But the whole defense has. And I do think it speaks to scheme. I think he is a quality starter at safety though. It is Williams, though, that is either a major regression or held back by a more passive scheme or both. Think back to the pick 6 vs SEA in the playoffs and there has been nothing close to that aggression from him in 2021.
I can definitely see Rochell growing into a CB2 role for 2022 but they are going to need more depth going forward. Unfortunately I dont think Long is any more than a CB4 at best.
