Analysis: OL has undergone overhaul

IRVING, Texas – When the Dallas Cowboys drafted Tyron Smith, David Arkin and Bill Nagy last year, in addition to adding Kevin Kowalski as an undrafted free agent, it appeared as if they were preparing for a youth movement on the offensive line.

After all, they cut Andre Gurode, Leonard Davis and Marc Colombo, too.

But with the team’s additions of Mackenzy Bernadeau and Nate Livings over the last three days that not no longer appears to be the case. It’s not that the Cowboys got old -- though Livings turned 30 today -- but they definitely got new.

Bernadeau and Livings received starter’s money from the Cowboys.

They also add size to the interior of the line, which was a problem last year.

Nagy started the year and checked in at 303 pounds. Costa is listed at 314 pounds. Kosier is listed at 305 pounds. Montrae Holland and Derrick Dockery, who replaced Nagy after the rookie suffered a broken ankle, checked in at 340 and 325 pounds, respectively.

Too many times the pressure up the middle bothered Tony Romo.

Carolina listed the 6-foot-4 Bernadeau at 308 pounds. Cincinnati listed the 6-foot-5 Livings as 332 pounds.

At first guess the line in 2012 projects to be, from left to right: Tyron Smith, Nate Livings, Phil Costa/Kyle Kosier, Mackenzy Bernadeau and Doug Free.

Now that’s quite an overhaul in a short amount of time.
