The new prevailing wisdom is supposedly that you don't pay a lot for a safety. SEA has been trying to get out of the Jamal Adams deal for a while, NYJ was happy to. There aren't many who are transcendantly good.
A few will get paid (Winfield), and a guy like Geno Stone will get offers but I don't it will be bank breaking.
I think one of Ford or Savage will be back unless they want to start over. Given Ford turns 30 this Nov they might decide on that. I expect Gute to go heavy in the draft at Safety, OL and RB. Hafley's defense will ask different things from its safeties, and GB didn't field a great group last year anyway.
