The Eagles traded away the 25-year-old Matthews, along with a third-round pick in 2018, to the Bills in exchange for cornerback Ronald Darby on Friday.
In three National Football League seasons, Matthews has caught 67 passes, 85 passes and 73 passes.
Darby, a third-year player out of Florida State, was originally drafted by the Bills in the second round of the 2015 NFL Draft.
Darby, who finished in voting for the 2015 Defensive Rookie of the Year voting, has two years remaining on his contract. And not long after the Matthews deal was announced, Schefter had some more news to share about head coach Sean McDermott's team. Whether it will have been worth it or not depends entirely on whether Darby rebounds and becomes a consistent starting cornerback for the Eagles. However, Watkins was hobbled over the 2016 season with a foot injury. Even in the touchdown drive in Thursday's preseason game, Matthews caught a short pass to pick up a key first down simply by having great field awareness, something the Eagles will lack with Agholor or one of the younger receivers who have stepped up in preseason camp. He had 121 tackles, 32 passes defensed, three tackles for loss, and two interceptions with the Bills.
Instead of the players the Bills received in return, the key to whether this trade will be successful for Buffalo is the draft picks they acquired. "We do what we think is in the best interest of the team then when you pull a trigger on anything like this, you think about the player you're giving up and the draft pick, but we felt like this was the right decision for us". Philadelphia did sign wide receivers Alshon Jeffrey and Torrey Smith in the offseason. The Patriots' pick could become a third-round if cornerback Eric Rowe, traded previous year, gets at least 50 percent of their defensive snaps.
Buffalo essentially traded Gaines for Darby in these two trades, as well.
