Marcia Coyle of the National Law Journal has the scoop.

  I wonder how (if at all) the picture changes if you focus on who wrote the briefs rather than who stood at the podium for oral argument. The media invariably focuses on who gave the argument, but most of the important work is done at the briefing stage. Of course, if there are lots of names on a brief, it's hard to tell who actually did the bulk of the work; focusing on who had the argument is much easier.
