I think Wigglesworth gets some unwarranted stick, he's a dependable option who you know what he's going to do and he'll do it without ****ing up. His pass is a hell of a lot better than Youngs (saying that, a list of "people who pass better than Ben Youngs" isn't exactly a short one ... ) and he's the best kicking nine around. I do have a problem with picking him specifically to counter Ireland's kicking game though - I think it's too reactive, you have to pay attention to your opposition, of course, but you also have to have the confidence to play to your own strengths. The best we've played in the tournament, probably in two years, was the second half against Wales, so our best chance of beating Ireland is to replicate that. That means picking Youngs, unfortunately it then relies on crossing our fingers that he has a good game, which seems to come down to a toss of a coin to be frank. I do worry about Ford's kicking (which needs to be at its most accurate) if he has to spend the day catching handfuls of dog **** thrown at him by Youngs ...
As for Goode ... if Brown isn't able to play (do we know anything concrete about that yet?) then it pains me to say he's probably a decent option - however I would rather see a more progressive choice, either Watson or Nowell, as both have areasonable chance of being an international class fullback in the future. If Brown is fit, then there is no way Goode should be anywhere near the team.
EDIT: Sorry, in case I wasn't clear - what I mean to say, is Ireland don't have a chance in hell of winning and will be lucky to get within 20
