How did Wales and England expose Ireland’s limitations?

If Carlsberg could do Grand Slam-winning opening salvos, they would replicate what Wales delivered in the opening 70 seconds of action in Cardiff last Saturday. If they could do championship draws, then the 38-38 extravaganza in Twickenham, after the Scots had trailed their English hosts 31-0, is about as outrageous as you could hope to witness. It’s been that kind of Six Nations championship.
All the sides, bar Italy, enjoyed some notable moments, but Wales were the only side that consistently delivered when the need was greatest. For that reason alone, they were fully deserving of their success.
