The Dallas Cowboys offensive line has historically been a central reason for their past success. Going back to the 1990s glory days, it was the impressive offensive line that helped Troy Aikman deliver so expertly and Emmitt Smith set NFL records. Then there was the reemergence of that dominance at the position just a decade ago when the likes of Tyron Smith, Travis Fredrick and Zack Martin led the way, giving Tony Romo some of the best moments in his career and helped Demarco Murray break NFL records.
Last season, however, was a tough year for the offensive line, mostly due to injury, but also it lacked that elite level of protection Cowboys fans have been accustomed to.
