Cooper is never, ever going to go on a speaking tour. He is one of the worst speakers I have ever seen, but that isn't what he is about. He is about playing rugby, using is instinct and intuition to break down defenses. Ever notice a familiar pattern with his brain farts? They generally come when he has time to think. See the trip. See the dropping of the ball in space against the Force. He isn't good when he thinks, he has instinct.
The last instinctive player (and also poor speaker) for the Reds was Chris Latham. Passion, drive and instinct made him a great player and despite his massive following, to my knowledge was never a great earner as far as 3rd party sponsors is concerned. In fact if you think about it, there aren't many current wallabies that have the big profile, prescence or charm that you need to have huge amounts of personal sponsors. No one comes close to the likes of Gregan for far ranging recognition, or Eales for recognition and respect. Giteau probably comes closest, but he too isn't the best speaker, and doesn't appear to be the brightest tool in the shed. If I had to pick a few that may make that mark it would be Genia and TPN, but both seem quite shy.
