Miami Dolphins seem to have an offensive line concern. But Mike McDaniel pushes back.

MIAMI GARDENS — The biggest surprise on the Miami Dolphins' initial 53-man roster may have been undrafted rookie center Andrew Meyer of UTEP.

"I get it, there's drafted guys, under-drafted guys, but at the end of the day, you've got to act like you're supposed to be here, otherwise you're never going to make it," Meyer said Wednesday, one day after making the 53. "You're going to lose already because you've got no confidence."

The Dolphins kept Meyer, in part, because projected starting center Aaron Brewer has a hand injury and is uncertain for the opener against Jacksonville on Sept. 8.

Miami could start projected starting guard Liam Eichenberg as center, if Brewer is not ready, but then Meyer would need to serve as the backup.

Citing competitive reasons, Miami coach Mike McDaniel declined Thursday to discuss details about if Brewer has been snapping. Reporters have not seen that yet.

"Well, yes, that's part of gripping, that's part of the process of his return," McDaniel said. "He's doing well and I'm very comfortable with his projection. What is that projection? Well, it's not league mandated. And it's no offense to you. It's more being responsible with competitive advantages."

If Brewer can't start, that weakens Miami because Eichenberg is probably stronger at guard.

Over the last two days, general manager Chris Grier and McDaniel have repeatedly defended the capability of Miami's highly-scrutinized offensive line.

"The group has given me more confidence at the O-line position really in general than I've had since I've been here," McDaniel said Thursday, double and tripling down on the notion.

Since he's been in Miami, McDaniel said.

Those are strong words.

The Dolphins should feel confident at tackle, with Terron Armstead and Austin Jackson starters and Kendall Lamm and Patrick Paul as reserves. But the interior of the line has a lot of questions.

If Brewer can't go, and Eichenberg starts at center, Miami would be one snap away from having Meyer, the undrafted center, in the lineup.

"I stopped worrying about depth charts," Meyer said of a key tip he received during training camp. "I was in my own head about it at the beginning. So soon as I got rid of it, I was good to go so that was the best advice given to me."

Grier believes if needed, Meyer could contribute.

"He's got personality, he's tough, he's smart, he loves ball, he's a grinder," Grier said. "And every day he just got better and better."
