It seems Roger Davis was the real backer of the Wiggs/Carrol takeover of RA, the other directors, while not opposed to Carroll, wanted due process. While some here have said we have to act quickly, we also have to go through the proper processes, this isn't a small private business. The history of the Tahs under Davis has been one of steady decline, he is one person who would be better right out of the running of the game.
I read GR's pieces in the SMH, she may be right, however it looks far more like Wiggs (who, I have to say, seems extremely competent) basically said you do it all my way or I'm out of here. If you look at his CV, he has basically spent most of his working life running his own show, so you can see where that attitude comes from. However, at RA you are not running your own show, you are managing the top end of the sport on behalf of thousands of stakeholders, and governance becomes crucial.
It seems Carroll has also taken the attitude that he will only take the job if it's handed to him, not if he has to go through proper processes. Again, everything I can research seems to suggest he's very competent, but to be appointed CEO on short notice without having even met half the board, I don't see how he thought that appropriate.
Interesting that Carroll also seemed to want to select his own boss! Happy to work under Wiggs or McLean, but if it's not one of them he's out.
