In a series of articles over the next few days, Football Outsiders will be looking division-by-division at the biggest weakness left on each team's roster after free agency and the 2015 NFL draft.
This edition examines the NFC East.
Biggest post-draft weakness: Safety
It would be nice if Dallas could add a runner to replace DeMarco Murray, but it's clear that you don't need a dominant running back to win a championship in today's NFL. You do, however, need great play from your defense -- or at least better play than what the Cowboys got last year when their defense finished 22nd against the run, the pass, and overall by Football Outsiders' DVOA metric.
The additions of free agent Greg Hardy (pending his suspension, which is currently slated for 10 games) and second-round draftee Randy Gregory should boost the pass rush, while first-round cornerback Byron Jones will help Brandon Carr and Orlando Scandrick handle spread formations. At safety, though, the Cowboys are stuck with the eminently mediocre duo of J.J. Wilcox and Barry Church.
