The Dallas Cowboys have been regarded as having one of the best offensive lines in football over the last several years. If they weren’t the very best during a given year, they were real close, and year after year they were always finishing near the top. But that wasn’t always the case.
Prior to Jason Garrett taking over as head coach, the offensive line was ranked ninth in the league according to Pro Football Focus. The group consisted of four starting offensive linemen who were 32 years old - Marc Colombo, Leonard Davis, Andre Gurode, and Kyle Kosier.
