Eventual O-Line Vulnerability?

Our run blocking is elite. It is currently nearly unstoppable and has the league in a frenzy to stop it. The issue is, what if a team DOES stop it? What if we get behind and are forced to pass? We get lucky on home runs but the line is not built to pass block. Im worried about this one dimensional aspect of our line if a team goes up on us a couple scores and tees off on our line forcing us to pass. We are so starstruck by the rungame we need to consider what happens if its not going so well.
You have to trust that Kubiak will find a way to change it up and he will, but I think from just what we have seen early the passing game is good enough to get the running game going if it slows down.
