Shaun Edwards joined the Welsh Rugby Union as assistant coach (defence) on 14 January 2008 and thereafter, Wales conceded just two tries in 400 minutes in winning the 2008 RBS 6 Nations Championship and Grand Slam.
Wales were similarly miserly in the 2012 championship, conceding just three tries, and none at all, in the final three Tests against England, Italy and France.
Across a period in the 2013/2014 RBS 6 Nations, Wales set a new defence record by not conceding a try for 400 minutes.
Edwards made 467 appearances for Wigan, scoring 1,140 points and won the Challenge Cup eight seasons in a row and nine times in all in an illustrious rugby league career. He also won eight championship titles. He played 36 times for Great Britain, scoring 16 tries.
As a coach, his trophy tally at London Wasps included two Heineken Cups, four English Premiership crowns, one European Challenge Cup and an Anglo-Welsh Powergen Cup triumph.
