Play Etling and let MB get meaningful reps. Move him along as he is ready so he'll be seasoned for next year. Hell the way the line is blocking he might have to finish the season ala Shea Patterson. I wish Etling no harm but as thin as we are up front it might get ugly
I agree @Kikicaca thats why we have time with Brennen. Cook him slow like Gumbo and he'll be ready for next season.
