The Eagles were the only team in the NFL that didn't have an "outside" receiver with more than 50 targeted passes last season. Most teams had two. Some had three. The Eagles, for various reasons, didn't have a consistent threat outside the numbers or downfield.
Only two of four regulars from last season remain on the roster. Riley Cooper was released last month and Miles Austin was mercifully cut with five games left in 2015. Nelson Agholor and Josh Huff return, as expected, but neither was drafted by new coach Doug Pederson or returning general manager Howie Roseman, per se, so their futures aren't as clear as if Chip Kelly had stayed.
