Despite being a Scotland supporter, I have just about talked myself into backing England in tonight's rugby world cup final.
My reasoning is as follows. Last night's third place play off, in which Argentina convincingly beat France, was excellent for its own sake, showing the coming of age of a rugby nation outside the traditional eight 'founder nations'. But it also means that if Argentina beat the French by 24 points, whereas they only beat Scotland by 6, then clearly the Scots are 18 points better than France. By contrast England only beat France by 5 points, which makes Scotland 13 points better than England.
So, by my reckoning, if England win tonight then morally that makes Scotland world champions - something that I am sure Jason White and Co will confirm in next year's Calcutta Cup match in Edinburgh.
