Ireland don't have the player pool to just do a France and reset and put the kids out with an aim for a World Cup four years later. The way we've done it so far has brought success and I'm not sure what else people want. If a team was meant to win the 6N every year it would be France or England, and that hasn't happened so we shouldn't really criticise the approach too much. People saying ah why are Murray, POM and Healy still around - think people forget these are generational talents, there are so many other players who have 10/15 caps only (see England). These are all proven lions players - not just there making up numbers.
I think perhaps Ireland are slightly too conservative in giving young players a random shot (other than SP). I feel other teams have found great players sort of randomly through this and sometimes you just need to roll the dice.
