Training camp battles: left guard

With the start of training camp coming next week, we review the five biggest position battles with the Dallas Cowboys.

Left guard

The favorite: Ronald Leary

The contenders: Mackenzy Bernadeau

Outlook: This battle was set up when the Cowboys drafted Zack Martin in the first round and decided to move him to right guard. It meant Bernadeau lost his starting spot and had to fight for a job with Leary. Leary started all 16 games in 2013 and performed well. The Cowboys like competition at various spots, especially if it means improving the position and Bernadeau will compete. Bernadeau lost his job at right guard to Brian Waters only to regain it when he suffered a season-ending injury last season. Bernadeau is still a quality offensive lineman and has shown his versatility by playing both guard spots and some center. Regardless of whether he gets the starting job, Bernadeau is needed along the line. The Cowboys won't invest in a veteran player for the offensive line, like Waters, because the team wants a younger lineup at several key spots.

Who wins? It's a close race, but expect Leary to maintain his spot. Bernadeau will morph into a player who can play several positions and this will help the line overall.
