Guard isn't even my concern with the OL

That would be Boom being able to hold up to facing the best every week and to stay healthy. For a guy with Bruss' film to slide into RG between a stud like Hav and a solid Center I don't anticipate any issues. He'll probably kill it for us and at the least will be solid and improve as the season unfolds.

So my concerns in order are Boom > run game potency. If those two things work out I think the line will be just fine.
