Really hard to predict just who teams are going to let go in this salary cap climate. I made a list of rumored cuts and then added guys from teams I feel have depth where they would rather have a late round rookie as their #3 back. I put them in tiers. I personally would rather re-sign Williams if possible and draft a back in the 6th or 7th round. Without Williams probably need to address RB in 4th or 5th.
Tier 1
Lat Murray- will probably cost more than Williams
Mack or Hines- can the Colts keep both behind Taylor?
Tier 2
James White/Rex Burkhead- thinking one of them could be available
D. Williams or D. Williams- if Damian opts back in KC can afford to lose one
Jackson or Kelley- longshot but Chargers may let one go
Brown or Henderson- it is clear who the Rams #1 back is
Tier 3
Justice Hill
Wilkins- see Colts above
Royce Freeman
McKinnon/Coleman- deep backfield- McKinnon is my #1 hope to get on the cheap
R. Penny
C. Thompson
C. Clement
