For the first time since Jim Johnson was running things the Eagles have a shutdown defense.

With a genius in charge.

So, how long will the Birds be able to retain defensive coordinator Jim Schwartz before he gets plucked to be a head coach again?

With previous head-coaching experience, Schwartz likely has the best chance among Philly coaches to capitalize on the Eagles’ 3-0 start.

And that takes into consideration that owners of quarterback-needy teams are enamored of the progress of rookie Carson Wentz under offensive coordinator Frank Reich (and obviously, head coach Doug Pederson, as well).

Philly has road games against the Lions and Redskins on tap, before returning home for a huge test vs. the Vikings. The Eagles could meet Minnesota at 5-0, especially if they maintain one of the league’s most efficient defenses.
