Bishop is certainly going to be the starter moving forward at one safety spot. He is a quality safety with upside to be one of the better ones in the league. Rapp was never more than backup quality, the same with Hamlin. At this point in his career, Poyer is probably the equivalent of Rapp. Hancock may be the future at the other safety spot. He's done some good things, but I think it's a bit early to know his ultimate ceiling. He might have solid starter potential. If the Bills don't add a quality safety or draft one with potential, they will probably be OK next season, but I think they would be better off if they did add someone.
