I would say we do have some pieces on defense...
We were actually ranked the # 1 Secondary in the NFL by PFF a week ago
1. Dallas Cowboys (Rank entering Week 7: 4)
Top overall grade: S Barry Church, 86.2 (No. 9 among safeties)
Top coverage grade: CB Morris Claiborne, 85.1 (No. 12 among CBs)
Top run-defense grade: S Barry Church, 86.0 (No. 11)
Most snaps: CB Brandon Carr, 1,013
One of the biggest reasons for the Cowboys’ success this season has been the turnaround of the secondary. After having just one defensive back with an above-average coverage grade last season, all eight players with at least 100 snaps in 2016 earned average or above-average overall and coverage grades. Although they lack an elite-caliber player, this group has played consistently well as a unit. Byron Jones, Barry Church, Morris Claiborne, and J.J. Wilcox have all earned career-high overall and coverage grades this season, while rookie Anthony Brown has played well down the stretch in Claiborne’s absence.
