Mel Kiper mock: Cowboys take OG Chance Warmack

ESPN's NFL Draft expert Mel Kiper Jr. has the Cowboys taking Alabama guard Chance Warmack at No. 18 in his latest mock draft (Insider).

It's a logical selection, given the Cowboys' inconsistency along the interior of the offensive line last season.

Cowboys director of pro and college scouting Tom Ciskowski is scheduled to attend Alabama's pro day Wednesday. No word on whether coach Jason Garrett will show up. He attended last year's pro day in Alabama and has a close relationship with Crimson Tide coach Nick Saban. Now, just because Garrett watches a pro day doesn't mean the Cowboys will draft a player from that particular school.

Garrett doesn't attend a lot of pro days. However, he did attend USC's in 2011 with former offensive line coach Hudson Houck. The Cowboys selected tackle Tyron Smith in the first round that year.

The Cowboys' offensive line is an area of concern this offseason. While the team believes it has a solid left tackle in Smith, the other four positions have issues.

Guards Nate Livings and Mackenzy Bernadeau were signed as free agents last year and had an uneven first season. Centers Phil Costa and Ryan Cook will return, but injuries limited Costa to just three games in 2012.

Right tackle Doug Free shared playing time in the last month of the season with Jermey Parnell.

According to ESPN's Stats and Information, quarterback Tony Romo threw an NFL-high eight interceptions when under duress last season. That can be attributed to the receivers, Romo holding the ball too long and the offensive line.

Whatever it is, improving the offensive line is something that must be done in 2013.
