According to his biographer Martin Breheny, what you see is what you get with Kilkenny senior hurling manager Brian Cody… I've sat around the All-Stars selection committee table with him for the past 20 years… He raises the subject of Cody's biography, which he ghosted, without having to be prompted. It was criticised for being bland and uninformative and not revealing secrets; Breheny's counter-argument is that Cody doesn't do secrets, that there's nothing arcane about his recipe for success and that in this instance what you see is very much what you get. 'People criticised it for not showing the Brian Cody they thought existed. But they were trying to impose their own view of him. The Brian Cody in the book is him'.
