The reason getting most juice for why the Philadelphia Eagles currently stand as the class of the NFC is improved play from second-year quarterback Carson Wentz. But the Eagles’ 10-1 record in 2017 is bolstered as much by its top-three defense, with improved run-stopping up front and superior cornerback play from newcomer Ronald Darby and Jalen Mills, a 2016 seventh round pick who developed after spending his rookie year behind Leodis McKelvin.
With those two corners manning the boundaries (plus Patrick Robinson in relief of Darby earlier in the year), Philadelphia is fourth in DVOA against passes to the right side and third against passes to the left.
