It seems to be assumed by those who think they know about these things that Wales will have no trouble in beating Italy next week - I am never so sure about these "sporting certainties" - and will therefore set up a very significant game against England at Cardiff for a week or two later.
It seems from the Graun's article that Wales' win yesterday was the biggest turn-round ever in the history of European/British rugby. I'm not a fan of these records as when I first started watching rugby over 50 years ago the try was only 3 points so you have to analyse the result in order to make a fair comparison. I had in my mind England v Wales 1970 as a bigger turn-round as I recalled, incorrectly, that England had been 13 - 0 (two converted tries and a penalty) up when Gareth Edwards was taken off injured and Chico Hopkins replaced him. I knew that Wales had won 17 - 13, but I had sadly forgotten about Mervyn Davies' first-half try*, which brought the score back to England 5 - 3 Wales. Wales scored 4 tries, 1 conversion and one dropped goal, so under today's points values, that would have been 25 - 17 to Wales. But Mervyn Davies ruined it...
