My list:
Cato June - this guy played strong safety in college. Sign him and put him at Rodney's position, move Rodney to FS and Eugene to CB. I know, how could we? But June is an extremely talented player whose talent we could appreciate in the coming years.
Michael Lewis - If not Cato, let's sign this guy. Lewis will be a free agent, as he has fallen out of favor, but his hard-hitting talents could be used in our system.
Ken Hamlin - And if we can't pick up Lewis OR June, let's pick up one of the most underrated players in the game to stop the deep threat at FS.
Adalius Thomas - can play anywhere on defense, save defensive tackle. An extremely valuable asset.
Roderick Hood - up-and-coming player (only 25 but has four years of experience) who will not get used in his current system, with Lito Sheppard and Shelton Brown ahead of him on the depth chart.
Daniel Graham - there is no reason not to resign Graham. He clearly wants to be here and we can still use his talents.
