The Redskins need to focus on upgrading the O-line in this FA period. Fortunately the T's in this FA all of a sudden got a lot stronger with the recent cuts of some good young RT's so here is my wish list
RT Eric Winston is my top overall Free agent choice
other notable if cant sign Winston : Levi Brown, Anthony Collins
G Ben Grubbs is my top G i would like to sign
ILB it does not look like the team will sign London Fletcher but there are some pretty good options on market.
Henderson, McClain will be more affordable.
and that would be about all i would look to do in FA i think you could fit signing one guy at all those positions
RT,G, ILB, C they would have to get a little creative with the contracts with the reduction of the salary cap.
