Book excerpt: Throughout the history of rugby union, a select few players have stood out above the rest. Bringing together 50 of the finest, this book reveals the fearless scrum-halves, tricky wingers, explosive centres and powerful props that have lit up the game, celebrating their achievements and controversially ranking them in order of greatness. Is the might of Jonah Lomu preferred to the vision of David Campese? Who was more influential, Jonny or Johnno? Which hemisphere has produced the most superstars? And most importantly, who will be named the greatest player of all time? Passionately argued, provocative, and sure to trigger lively debate, this book is a must-read for rugby fans everywhere. Published in time for the Six Nations 2016 and fully updated following the 2015 Rugby World Cup, hosted in England.
