As it is Day 4 of the NFL’s new league year, let’s step back and assess what Washington has done so far:

There are the moves the Redskins have made: Franchising OLB Brian Orakpo, re-signing ILB Perry Riley Jr. and WR Santana Moss, signing free agent DL Jason Hatcher, WR Andre Roberts, G Shawn Lauvao, CB Tracy Porter, ILBs Adam Hayward and Daryl Sharpton, and cutting P Sav Rocca, DL Adam Carriker and C Will Montgomery.

There are the moves the Redskins could still make, as free agent OLB Anthony Spencer, CBs Brandon Browner and Walter Thurmond, S Ryan Clark, DL Antonio Smith and WR Kenny Britt are still unsigned, as of this writing.

But as much as free agency is about opportunity, it can also be a time for missed opportunities. With that as the inspiration, which moves have the Redskins not made that you wished they had? Once you have the benefit of hindsight — you see the contract another team gave a player, or you see the moves the Redskins made at the same position, it can change your overall opinion.

Which free agent did the Redskins not sign that you wish they had? You can choose up to five answers.
