The problem is there are numerous versions of the WCO. That's like saying you can't win with the option offense in college football. Urban Meier built his success at Utah on a version, albeit a very unique one, of an option based offense.
The WCO is even more ambiguous b/c it has changed so much even since its inception with Bill Walsh. Basically its a short passing game mixed with a running game with a major goal of developing an efficient, ball control offense in the end. There are so many different ways you can do that its really hard to define.
Originally this staff was trying to build an offense similar to the Colts and I think they've switched somewhat after the Baylor game both in some of our schemes and in personel. Our hope has to be that those changes pay off in these last 4 games.
