September 1968 (a law previously used in Australia) "revolutionised full-back play". JPR Williams of Wales was the first full-back to regularly score tries after the law change, scoring six times in Five Nations matches in the 1970s. Notable full-backs include Serge Blanco, who scored 38 tries in 93 tests for France and was known for his counter-attacking ability. In 1997, he was among the inaugural set of rugby players inducted into the International Rugby Hall of Fame and in 2011 he was also inducted into the IRB Hall of Fame. Four full-backs who played for the British and Irish Lions are in the International Rugby Hall of Fame; Gavin Hastings (also inducted into the IRB Hall in 2013) and Andy Irvine from Scotland, Tom Kiernan from Ireland and the aforementioned Williams. Hastings and Irvine were accurate goal-kickers and Kiernan is credited with being the first attacking full-back in Irish rugby. Williams was chosen as the greatest Lions full-back at the inaugural Lions Legends Dinner at Lord's in 2008 and is praised for his safety under the high ball, tackling and calm decision making. The other full-backs in the International Rugby Hall of Fame are Don Clarke and George Nēpia from New Zealand. Clarke, nicknamed "the boot", was an accurate goal kicker and Nēpia was noted for his tackling and kicking ability. Three-quarters Wing The wings are generally positioned on the outside of the backline with the number 11 on the left and the number 14 on the right. Their primary function is to finish off moves and score tries. Wingers are usually the fastest players in the team and are either elusive runners or, more recently, big, strong and able to break tackles. The skills needed for the left wing and right wing are similar, although left-footed players are usually played on the left wing as they can step and kick better off their left foot. The winger on the blindside often "comes off the wing" to provide an extra man in the midfield, in the same vein as a full-back. One or both wingers will usually drop back on opposition kicks to give the full-back extra options for counter-attacking. There are a number of notable wings throughout history. David Campese, a member of both the International and IRB Halls of Fame, played 101 times for Australia and held the world record for most tries in test matches. He was
