I wouldn't agree, both the center and tackle positions are keeping them from being on-par with the top contenders, that's 40% of the line, including the all-important middle. There are times when Dallas gets close to winning because Dak is balling-out but he can't do that consistently, it's a high wire act where the wheels can fall off at any time and often do against better teams. Look at the top teams this year and compare OLs,,, every single one of them has a better OL. Throughout the course of a game, and throughout the season, those teams don't have to do the high wire act, the percentages are with them, and they win.
