What teams will we be scouring waiver wire for additions? OL & CB particularly

I am assuming Packers for oline depth for sure based on what I have read. Possibly CB there as well. Dallas for oline depth? Eagles might have a solid RB for us to pick up if they keep that kick returner.Any thoughts on this? I am assuming we definitely add a center/guard and CB off of waiver wire and possibly a DE and OT as well.Hard to find teams with extra defensive ends but maybe Buffalo again?Havent spent time looking at rosters as previous years thus the question.
