Got this from the roster section of this website and just put them in order of position. Did n`t differentiate   the LB`S as OLB or ILB or CB and S.I tried to list them in order of importance to the team at each respective position and figured it might be a way to speculate which 53 make the final squad. Let me know if some of these players have already been released or if I missed any.
