The Dallas Cowboys are sitting in pretty good shape along the offensive line. And considering they’re coming off a season where every one of their starters not named La’el Collins missed some time, that depth certainly comes in handy. The team called on their reserves quite a bit last season as players like Joe Looney, Cameron Fleming, and Xavier Su’a-Filo all saw plenty of action last year. Filling in for Travis Frederick after he was diagnosed with Guillain-Barré syndrome, Looney started all 16 games at center. Replacing Connor Williams at left guard, Su’a-Filo started eight games.
