According to Jason Cole, for whatever his "professional" opinion is worth, the Dallas Cowboys have the 10th ranked offensive line. He claims to have come to his rankings taking into consideration data complied from Football Outsiders.

Quick NFC East Glance:

Giants - 8th

Cowboys - 10th

Eagles - 18th

Redskins - 29th

Dallas Cowboys: When things are going good with the Cowboys, the running game is clicking and quarterback Tony Romo(notes) is able to operate behind this mauling unit of behemoths (side note: guard Leonard Davis(notes) might be the most imposing figure in the human race). However, when this team is behind on the scoreboard, the offensive line can look like a band of turnstiles, as it did in the NFC playoffs at Minnesota. That turned Romo into the second-coming of Chuck Wepner. This is the ultimate feast-or-famine line in the league. Left tackle Flozell “Kick Save” Adams is gone, which will be an issue. Adams is far from irreplaceable, but finding a new one is no easy task.
