Why a concern? He's still developing. OL nearly always do.

He wasn't all that bad. And it's your take that he had a bad game against GB. I don't think he had such a bad game. The entire team played poorly that day.

Besides, the Rams OL staff has continued to say that he is developing well. And he's sure no turnstyle. He's still learning to play OG. Just be patient. He'll likely do fine. Besides, a good Oline is always better than the sum of it's parts. It's how they play together as a unit.
