In the secondary, the Cowboys are mostly a single-high team these days, meaning that they play with a designated free safety and strong safety. Xavier Woods, a second-year player from Louisiana Tech (who I really liked in college), is the free player and is typically in the deep part of the field. Veteran Jeff Heath is the strong safety. He's a player the Eagles have attacked in the past and I think they'll look to do it again if given the opportunity on Sunday night.

At cornerback, the Cowboys have a converted safety in Byron Jones at right corner, and he's their best cover guy. He's long, physical, and athletic with plus ball skills. On the other side, Chidobe Awuzie and Anthony Brown have been the starters, with Brown typically as the nickel corner in their subpackages. Jourdan Lewis, who has moonlighted as an offensive skill player as well, gets time on defense. Their "big nickel" package with three safeties includes young veteran Kavon Frazier in the slot.

These may not seem like household names, but no defense in the league has allowed fewer big plays in the passing game this season than Dallas. The Cowboys have only allowed 17 receptions of 20 yards or more. This is a tough defense, to be sure, and one that the Eagles have to be fully prepared to handle on Sunday night, particularly up front.
