The best NFL free-agent signings aren't always the ones you expect.
Look at the Philadelphia Eagles, who just finished their first Super Bowl parade. Yes, they paid Alshon Jeffery a boatload of money to become their No. 1 receiver, but it was the less-heralded acquisitions that really put the Eagles over the top.
Stealing running back LeGarrette Blount and edge-rusher Chris Long from the New England Patriots; signing receiver Torrey Smith and defensive tackle Timmy Jernigan. These signings, though they didn't make much of a dent in the news cycle, were crucial for the NFL champs.
