Your starting defense with what we have right now.

[Bilbo Saggins]

Wouldn't base be Big Nickel? I see:

NT - Reader
3T - Atkins
DE - Dunlap
DE - Hubbard

Mike - Pratt
Sam - Bynes
Big Nickel/Will - Bell

CB - Waynes
CB - Jackson

FS - Bates
SS - Williams

Bell or Bynes would go out for Alexander against teams who lean on their slot receiver.  Reader and Hubbard could rotate out for Glasgow and Lawson on 3rd and longs.  I don't see any pure 3-4 OLBs on the roster.
