I agree, dagies. There's a reason the position is called defenseman. The player's primary responsibility is defense, not offense. As a group, I wouldn't trade UND's defensive corps for any in the nation. And I wouldn't trade Jones and Greene for any pair in the country.
David Hale never put up great offensive numbers and maybe never will. But that didn't mean that he wasn't one of the top defensemen in college hockey. Try telling that to the New Jersey Devils.
Is it good to have an outstanding offensive defenseman or two on a team? You bet it is. Is it a necessity? As of right now, the Sioux are proving that it's not.
