The Cowboys firm grasp on the title of “best offensive line in football” has loosened quite a bit with the reshuffling they have faced in recent years. Since the news broke about Travis Frederick’s condition that has no timetable for return, people just haven’t been as confident in this squad. When you’ve been a team that has three players on one unit that are arguably the best at their positions, any changes are going to cause panic. This is a team that is built on their offensive line. Without an All-Pro center, a career backup in his place, while also starting a rookie at left guard, there is certainly cause for concern.
