Eagles acquired CB Ronald Darby from the Bills in exchange for WR Jordan Matthews and a 2018 third-round pick.
The Eagles were clearly ready to move on from Matthews, so using him to acquire a talented, young corner with two years left on his deal looks like a no-brainer. Outstanding as a rookie, Darby had a bit of a downturn last season, but he is still easily the best corner the Eagles have on the roster and upgrades what already looked like a stout defense. If Sidney Jones is able to fully come back from his Achilles' injury, the Eagles could have a solid corner duo for years to come.
