He's right about Vaughan, and deep down we all know it. However, Moores is desperate and is likely to be influenced by the growing media criticism of his "leadership." Besides Vaughan is still technically under contract. He'll goes to the Windies for sure.
On his day Vaughan is a delight to watch. But his day was at least two years ago. If he goes to Oz, he'll be eaten alive, and that would probably hasten his retirement from all forms of cricket.
