Greg Alexander - Penrith Panthers great and one of the NRL's leading commentators and broadcasters on Fox Sports - joins Martin Devlin on It's Only Sport in a very special interview, covering off a variety of rugby league topics as the State of Origin period approaches. In a career spanning 15 years, Alexander played 265 first grade games and represented both New South Wales and Australia, and captained Penrith to victory in the 1991 NSWRL Grand Final. He and Devlin talk about the Warriors' surprise 22-20 victory over the Panthers, Brad Arthur being sacked as Parramatta Eels coach, selection headaches for the Blues with Origin 1 just two weeks away, and more.
