Is Mackenzy Bernadeau's starting job in jeopardy?

IRVING, Texas – Right guard Mackenzy Bernadeau knows he needs to play better, but he’s not concerned about losing his starting job.

Owner/general manager Jerry Jones hinted on his Tuesday radio show that Derrick Dockery could get playing time, but Bernadeau said he has continued to get all the practice reps with the starters.

“I feel like I’ve got to compete and do what I’ve got to do,” Bernadeau said. “If I do what I’ve got to do, there’s nothing else to worry about. Unfortunately, I’ve been doing my job, just not to the best of my ability. So I’ve got to get on my track to be the best that I can be and help my team be better.”

According to Pro Football Focus, Bernadeau grades out 68th among 71 offensive guards who have played at least 25 percent of their teams’ snaps.

Bernadeau has especially struggled in pass protection. He said he is focused on being more aggressive in his pass sets.

“There’s a difference between being aggressive and passive,” Bernadeau said. “Coming from another team, sometimes you sit back in a pass set and fan everything out. Here, we’re more aggressive, more firm and stout in the pocket. That’s something else I’ve had to adjust to, but we don’t have time. It’s something that just needs to be done. I realize that and it’s something that I’m working on.”

Bernadeau, who lost his starting job in Carolina before last season, missed all of offseason workouts due to hip surgery after signing a four-year, $11 million deal with the Cowboys in free agency. He also missed much of training camp and the first two preseason games due to knee surgery.

“I’m not the one to use that as an excuse,” Bernadeau said. “It definitely helps, though, technique wise. When you come into a new system and new team, you’ve got to learn the technique. At the same time, you’ve got to be professional about it. No matter how much time you get, you’ve got to do your job.

“Yeah, it definitely would have helped, but we’re a couple of weeks into the season now. It’s almost Week 6. You’ve got to go forward and not use that as an excuse.”
