There's A Reason Jake Brendel

was able to step in so effectively for Pouncey. He's taking most of the 1st team practice reps so he's used to playing with the 1st team. We got a chance to really see our depth up front in this game.

IIRC He was good/showed upside in Dallas. Remember him there. Just that they had Frederick and place a huge value on their backup OL being able to play multiple positions(poorly lol). So, I think the guy does have a shot at being a decent starter for the Dolphins.
Good point on him not looking out of place. Chemistry and reps matter, especially for young guys.
