Disagreeing With Chief Justice Roberts

Geoffrey R. Stone, a University of Chicago law professor, writes about Chief Justice Roberts and the Role of the Supreme Court. He doesn't agree that narrow opinions are good because the court is supposed to provide guidance, and if a ruling is narrow it provides only narrow guidance. I've heard Scalia echo similar thoughts. He also cites that unanimity is overrated as many concurring and dissenting opinions have been some of the most influential.
