'When two men go up for the mark, only one can find true happiness.' Guru Bob is one of Australian Football's most revered and incisive commentators. Well-known from his 'appearances' on the Coodabeen Champion radio show, the guru has much wisdom to impart on subjects such as winning and losing, sports injuries, umpires, Tony Lockett, Kevin Sheedy, David Boon and the art of war.
