Fair do's mate. I don't think the TV / pub explanation is that likely. I'd have been surprised if the pubs weren't full that night in November. Just a hunch. Maybe some of the rugger heads watched the GS game on BBC instead? But then again, maybe some Irish watched the Paris game on SKY (less likely).
I actually think I've been pretty balanced in these exchanges. I may come across as anti-rugby, which couldn't be further from the truth, but I think it was Jinxy who said many rugger types look down their noses at soccer, and some in the press certainly do. I agree, and this is what I'm reacting to, and why I say that the perception does not fit the reality.
But if I may say, you seem to be a bit of a single-issue-candidate. You seem to enjoy starting threads like "Why have the public deserted our soccer team?", when the answer was probably provided by Eamon Sweeney - they have always been up and down - and others here.
