Over the first three games of the season the Cowboys have faced some great defenses that have stressed their vaunted offensive line. In looking at the front 7’s of the Giants, Broncos, and Cardinals you notice that they are primarily built around their edge rushers, with premier talents like Von Miller, Chandler Jones, Olivier Vernon, Jason Pierre-Paul, and Markus Golden. Each of those guys are among the best, and in some cases are considered the best at their respective positions. Needless to say, the offensive tackles of the Cowboys have faced some stern tests in the early going of 2017.
