I didn't read any of the papers, only the BBC's online report which was all about the English underdogs sticking one on the Irish against previous form. I haven't seem much speculation about how it might affect the two teams' prospects at the World Cup except that losing would have been a psychological blow against England.
Do you mean this one:
https://www.bbc.co.uk/sport/rugby-union/47105622Which reports on the match, but mentions zero about the result in the context of the 6 nations as a tournament, but says the following:
'The silver lining for Ireland, if there is one, is that it is February not October. Better to be ransacked now than come the World Cup.'
'Expectations may be lowered a little. There will be less talk about going to the World Cup as close to favourites. These are good things. They are still the world team of the year, with the world coach of the year, and the world player of the year.'
And Jones even states that he sees this game as 'stand-alone' - hmm, not really consistent with someone talking about the first game in the best tournament in the world. The quote:
'"These games have got nothing to do with the World Cup," he declared afterwards, trying to keep that grin off his chops. "They are standalone games. We'll start worrying where we are in the World Cup 10 days before our opening game against Tonga."'
And in the interview he is specifically asked "stop the search - have you found your number 12 for the World Cup?"
