Even with WR Riley Cooper, the Eagles lack a reliable No. 2 wide receiver to complement DeSean Jackson and Jason Avant in the slot.
Their transition to a tight end-oriented system will be even more pronounced, and look for James Casey and Zach Ertz to play major roles with Brent Celek.
The Eagles don't plan to go outside the organization to replace Jeremy Maclin, which was a huge loss. With Cooper now in trouble for a racial slur, it makes sense the Birds look for more production from what is a deep group of tight ends. Celek probably has the most value of the three but it appears he could lose some work to the versatile Casey and rookie Ertz, who has even lined up on the outside at times in camp.
