Sometimes our passing is poor. Sometimes we panic clear for long spells , but that doesn't make us the 'worst passers' and more than the pointless stat does.
I'm not sure that keeping the ball always wears the opposition out. We are one of the strongest finishers to the game for a start.
I also noticed that Wales against Ireland's were working really hard passing the ball around in our own half whilst Ireland were happily jogging in between.
Again, it's all in context. At times on Monday Reading had us running around in circles, but on many occasions just made passes which put their defence and keeper under pressure and had to put in a lot of effort to clear in the end. Our passing overall was more effective and done in danger areas. Ironically Reading caused us most problems when they knocked it long behind us for their wingers to get onto, often forcing set pieces which of course got them their 2 goals.
It's far ,far more complex that the stars can explain
