Don't think we re-sign Kearse. Not sure on Mukuamu. I don't know if Zimmer will see him as a free safety, like Quinn did, or try moving him back to corner. I thought he played pretty well as the slot corner in the playoffs two seasons ago, but didn't think he looked good there last preseason. Still, if we don't re-sign Gilmore, which I don't expect him to do, we could use a player who can possibly contribute at two positions (FS and NB) in a pinch.
I see our depth in the secondary being:
CBs Diggs, Bland, Lewis, Mukuamu and Scott (whether Mukuamu would be the fourth corner depends on the development of Scott)
FS Hooker, Thomas and Mukuamu
SS Wilson, Bell and Thomas
