2. Richie McCaw (New Zealand)
A former captain of the All Blacks and generally recognised as one of the greatest all-time flankers, McCaw had the size and strength to be a punishing defender and the cool head and quick hands required to master the breakdown area. He became the first All Black to reach 100 Tests in 2011 and captain a century of tests in 2014. He won World Rugby Player of the Year a record three times (2006, 2009, and 2010).
