On Cluxton (and Morgan), I think both take responsibility for the kick out. Some keepers can never have a bad kick out because it is just safely lumped out to the middle each time. It might come back in again quickly, but that isn’t seen as the keepers issue (unless it was Cluxton).
What is important is the overall percentage we gain advantage from them, and I suspect Cluxton’s numbers are well ahead of everyone else, especially if you could put a weighting on what sort of advantage (Kilkenny free in his own half is better then a short one that travels 15m). With responsibility though comes accountability and Cluxton will be held accountable at time.
But both Cluxton and Morgan have the two important facets required, accuracy and time to destination. It’s not a target kicking contest. It is happening in a live situation. Most keepers can land the kick where they meant to, but very few can get it there as fast Cluxton or Morgan. If either is kicking to a free man, he is usually still free when the ball arrives.
It is going to go wrong on Cluxton sometimes, he can’t get it right every time. Also, I have noticed, if in doubt he will kick it to someone who will call for it - even if that guy is surrounded. But that is as much the guys fault who called as anyone’s. One of the most important things of last weekends game might have happened just at the end of it, he kicked a difficult enough one out to Shane Carthy, who gathered it against the odds. That might not be the last time we see that this year.
