Matthews was the team's focus at receiver because the Eagles have lacked any real presence on the outside since Chip Kelly let Jeremy Maclin walk out the door after the 2015 season. He intercepted two passes as a rookie with the Bills and started 14 games in 2016, logging 69 tackles and deflecting 12 passes.
The Eagles entered the offseason incredibly thin at corner.
The deal speaks well of Matthews' three seasons in Philadelphia and what he accomplished since being drafted in the second round (42nd overall) in 2014.
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. And not long after the Matthews deal was announced, Schefter had some more news to share about head coach Sean McDermott's team.
Not coincidentally, Jim Schwartz was the defensive coordinator in Buffalo for Darby's rookie season.
Some of this might be reshuffling of some National Football League deck chairs - getting rid of good young players who won't get expensive contracts for other good young players who might - but for the Eagles, it took their primary problem in the secondary and made it disappear. Certainly we know the production he had. "We do what's in the best interest of the team, and then when you pull the 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 best decision for us".
Opinions on the deal will be understandably split, but the Eagles traded for a position of need and gave up a third-rounder and what they feel is a surplus player they won't be signing longterm.
Roseman said it was a deal that could not have been made past year because the receiver group wasn't as strong as he perceives it to be at the moment, especially with the additions of Alshon Jeffery and Torrey Smith.
