Agree with that last post. Not so sure about the "Wales underdogs" bit and IMO if they are, it isn't by much. You're worried about your front row, but I was worried about ours before the tournament even kicked off (we're just not as well served there as we've been for the past few World Cups) and we've yet to see whether the new midfield combo will work (I can see the thinking behind it but Joseph will be a big, big miss from the centre for us).
England to win, but I reckon the margin will be smaller than 15 points. My money would be on 10 or thereabouts.
