Inverdale is a prick. Even when he mentions other T1 games it's always in the context of what's happening with England, I remember a Wales/Ireland game in a recent 6N where he said something like "this is the game where we see who has the best chance to beat England" or something.
not to jump on a bandwagon, but he's a notroious prat. Represents everything that is wrong with England. He doesn't speak for the majority however and I suspect anyone with a genuine interest in rugby would have have at least some small interest in the result.
