A third-string offensive line and third-string QB Ben DiNucci makes all of the Cowboys' fantastic skill position weapons impotent with the possible exception of rookie CeeDee Lamb. The Eagles' defense is strong enough to take advantage of the Cowboys' extensive injuries. 
Carson Wentz doesn't need his top two tight ends nor DeSean Jackson to put up a huge number on the Cowboys' hapless defense that gives up the most points per game in the league and ranks last in run defense. 
A maximum effort should be forthcoming from the Eagles against this hated division rival knowing their bye comes up next week.
