Most of the focus during NFL free agency has been on the ridiculous contracts top-end players received on the open market. More than that, we’ve covered in detail players who simply might not live up to expectations on new teams.

It’s the nature of the beast in an NFL world where teams have a vast amount of cash to throw around. Overpaying for castoffs on other squads was surely prevalent during the first wave of free agency.

With that said, there were some top-notch under-the-radar signings. These are players that helped certain teams fill a need — creating a potential trickle-down effect in the process.

By signing veteran Pro Bowler Andrew Whitworth to take over as their left tackle, the Rams are now able to move former first-round bust Greg Robinson to guard. How will that define the team’s 2017 free agency period moving forward?
