Big Decision: Should Cowboys bench Mackenzy Bernadeau?

IRVING - Mackenzy Bernadeau played poorly against Tampa Bay, prompting a to-the-point meeting with offensive line coach Bill Callahan.

Callahan said he's told the right guard, a key free-agent acquisition in the offseason, that the Cowboys need him to play better.

No time like the present, because Chicago has a quality front four and defensive tackle Henry Melton, a Grapevine and Texas product, who will be lining up against Bernadeau and has three sacks.

If he’s doing his job, Garrett spent a chunk of time this week pondering whether Derrick Dockery should replace Bernadeau, who signed a three-year $11 million deal but missed much of the offseason recovering from hip surgery.

Bernadeau was supposed to be a big body who solidified the middle of the offensive line. But he's been part of the problem - not the solution - having allowed a team-high three sacks and five pressures.

If Bernadeau struggles against the Bears, then expect Garrett to give Dockery a long look at right guard during the bye week to make sure he’s ready to play, if needed, against Baltimore.

Should Bernadeau struggle early against the Bears, we shouldn't be surprised if Garrett replaces him with Dockery.

Four of the Cowboys’ next five games are on the road. The Cowboys can’t blow a home game against a mediocre opponent because Bernadeau can’t get the job done.
