The Eagles have one primary objective this offseason.

But their most obvious, glaring need is also one of the hardest areas to shore up overnight.

In the latest Inside the Birds, Adam Caplan and Geoff Mosher discuss how the Eagles fill their biggest void with free agency and the NFL Draft around the corner.
