Full disclosure: I grew up in an era of Husker football when it was blasphemous for a coach to say he was "spooked" out of calling a run play. Of course, that was when hard-nosed running defined the program.
It's difficult to establish a strong run game without firm resolve. Daily resolve. In too many instances — such as when Nebraska calls for passes on third-and-3 in four-down territory — a lack of commitment is evident.
