Originally I thought it would be a cool idea. Not so sure now. I think you will see a field just like the WGC events minus a few guys and I was hoping the Olympics might bring some new fresh blood to the forefront. I doubt it will be any better then Tennis or Cycling where the top pro's just win the medals anyways.
Maybe they could just keep it fresh by using only players 23 and under.
to the argument about Bolt, Phelps, Shaun white and Vonn , remember that being a professional in an olympic event means people really only know you from the olympics and they don't care about all the years in between.
