Collectively, Tyron Smith, La’el Collins, Travis Frederick, Zack Martin, and Doug Free make up the dominant offensive line for the Dallas Cowboys – the pride and soul of this football team. When Jason Garrett and the Cowboys committed to building this unit, they did so with a run of first round picks that has established Dallas’ identity for years to come. However, the Cowboys are going to have to be smart about the way they go about building the sustainability of this offensive line. While most of the guys mentioned above are set in stone, the backups currently on the roster will all be fighting for their spots come training camp. One such player is Chaz Green, who was drafted in the third round by the Cowboys in 2015.
