Agree with Hancock. He is roster lock. Last season Hamlin, Bishop, Rapp Edwards, and Lewis were on the intial 53. With Benford, Douglas, Johnson, Elam and Ingram
I think there are more spots than you think.
CB Benford, Hairston, White, Johnson and open could be Hancock or Hardy, Jackson, Ingram and Strong.
S Rapp, Bishop and 3 spots could be Hancock depends what position he plays through camp preseason. If he takes Lewis that still leave 2 open spots. For Hamlin, Forest, Lewis, and possibly Owens.
I get the numbers change each year but on a team that didn't have much roster turn over Safety and depth at Safety is the only real open competition on the roster. If a UDFA makes the roster its the likely only spot possible unless they find a return man.
