I thought Ireland looked very old at the World Cup, and I think your analysis is pretty fair - there seems to be a need for a new plan, and I don't think Farrell is the man for that. I'm amazed he got the job, and assume the Irish Union must be skint!
Wales had a gentle loosener, but looked pretty comfortable, and should be okay if they can get the back line can be put in play.
But, and it's a huge but for the previous line, the forecast for Saturday is very wet and very windy. It'll be complete mayhem, and O'Mahony may be the perfect man for the day.
