When talking about the best offensive line in the NFL, you are likely to mention the Dallas Cowboys first. Bolstering three Pro Bowlers, the Cowboys O-line is considered by many as the premier positional group in the league.
But Dallas has sacrificed three first round selections over the past seven years in order to obtain All-Pros at left tackle, Tyron Smith, center, Travis Frederick and right guard, Zack Martin. The talented trio, along with left guard Ronald Leary and right tackle Doug Free, made up the best offensive line in all of football last year.
