WHAT THE EAGLES seem to lack, most critically, is lethal weapons. Difference-makers on offense.
Maybe you can buy into the idea of a healthy Sam Bradford being productive behind an offensive line no longer hamstrung by Chip Kelly's easy-to-diagnose zone-blocking plays.
Maybe you can get behind the idea that bringing in Jim Schwartz as coordinator, adding Rodney McLeod at safety, and going back to the 4-3 can take the Eagles' defense all the way from horrendous to pretty good in one offseason.
But if you're going to build a case for the 2016 Birds as contenders, you also must sell the notion of the guys running the ball and the guys catching it being better than the running and receiving corps for quite a few NFC rivals.
