This has been UND's offensive problem for a long time. I understand the desire to run the ball, but not all game situations are suitable for running. Need an O-line (ours was ok to good), need a QB (our was good then regressed to bad), need an OC (ours was a second choice that probably was "forced" on the new HC to have a one-year trial period - a test he didn't pass IMO).
Now, wanting an O-line, QB, and offensive genius OC is what everyone wants but supply is limited. It's like saying a basketball team needs big guy down low. Yeah, everyone knows that and wants that, but that doesn't mean you're going to get it.
