I think Sean smith might cost to much, I would target Jhonson b/c he can cover and blake proved he is terrible at that.
So I target a middle area type contract like 4 years 14 mill for Tremaine, With Weddle's age and past history offer him 2 years 5 mill.
Dewayne Allen 4 years 11 mill.
NT I go via draft try trading up for A'shawn who can play nt/dt both 1 gap and the 2 gap as well as both de sides, ir could allow you to in your base put him at NT and force Butler to use a 3-3-5 as his primary nickel where he could get constant pressure from a 4 man front of tuitt robinson heyward and dupree at the edge.
or even rotate A'shawn with heyward and tuitt in the times he wants to go 2-4-5 and 1-5-5.
Apple or Fuller and there will be howard, burns jackson @ bradbury in the 2nd or 3rd.
