If they sign another edge, another CB, doesn't have to be break the bank versions of it. And draft Downs. This defense should be at least average IMO.
The defense IMO had four problems last year.
A. No pressure.
B. Bad secondary
C. No depth.
D. Bad coaching
Depending on who they sign
A. Pressure should be at least OK maybe even good assuming Armstrong comes back healthy. As wacky as it sounds early in the season they were one of the top teams in pressure.
B. I think the scheme should help the secondary especially for Sainristil. They need though still to add a corner IMO. I don't love this unit but if they draft Downs he can cover some warts.
C. The depth should be at least ok.
D. Fingers crossed as to the coaching but I like the Flores scheme a lot.
