Feel I've got to stand up for statistics here. I find Phil Clarke's stats stuff fascinating and for me it adds a new dimension providing a deeper understanding of what is going on in the game.
Statistics never lie, they are just numbers. As stated in other posts it is the inferences that you draw from them that can be incorrect.
Statistics underpin many scientific and engineering disciplines - for example, statistical techniques were used in the detection of the Higg's particle at Cern.
In the Wigan Salford game the statistics quoted did not include tackle counts, tackles missed and metres gained, which I think would probably have painted a different picture. The statistics quoted were too selective to provide a good overall picture of the game.
And the other thing as stated above the quoted game is just one example. Statistics is based on the mathematics of probability and as such you always have a chance of metaphorically rolling double six. I am sure there are occasions when all the statistics might point to one team winning and they do lose.
