and recorded a 6–6 draw against South Africa in Cardiff. The following year, Wales recorded their first Five Nations Grand Slam since 1952. Using only 16 players in four games, the 1971 side achieved their most notable win of the tournament in their victory over Scotland; after a last-minute try by Gerald Davies that reduced Scotland's lead to 18–17, flanker John Taylor kicked a conversion from the sideline described as "the greatest conversion since St Paul" to give Wales a 19–18 win. Wales contributed more players than any other team to the British Lions side that toured New Zealand that year. Those Lions became the only ones to win a series over New Zealand. In the 1972 Five Nations Championship, Wales and Scotland refused to travel to Ireland at the height of the Troubles after receiving threats, purportedly from the Irish Republican Army. The Championship remained unresolved with Wales and Ireland unbeaten. Although the Five Nations was a five-way tie in 1973, the Welsh did defeat Australia 24–0 in Cardiff. Wales next won the Five Nations outright in 1975, and in 1976, Wales won their second Grand Slam of the decade. Just like the first in 1971, they used only 16 players over their four matches. They repeated the feat in 1978 and, in the process, became the first team to win three consecutive Triple Crowns. Following their final Five Nations match of 1978, both Phil Bennett and Gareth Edwards retired from rugby. Wales hosted New Zealand at Cardiff Arms Park in November 1978, losing 13–12 after a late penalty goal by the replacement New Zealand fullback, Brian McKechnie. The penalty was controversial because New Zealand lock Andy Haden had dived out of a line-out in an attempt to earn a penalty. Haden later admitted that he and Frank Oliver had pre-agreed this tactic should they find themselves in difficulties. Referee Roger Quittenton was criticised by the press for failing to notice the dive, but he later stated that the penalty had been given against Welsh lock Geoff Wheel for jumping off the shoulder of Oliver. Quittenton later said, "Haden's perception is that his dive secured the penalty. That is a load of rubbish". Wales then went on to win the 1979 Five Nations with a Triple Crown.
