Hi @stimp1024 I think that England still have an amount of mental fragility when it comes to the big crunch matches. I think that there is a sense of entitlement running through the team and when things are going against them and they can't deal with it.
I was reading this morning that they have been working with a psychologist to get over being knocked out of their home World Cup at the group stages in 2015. This signals mental fragility to me.
I also skimmed an interview with Kyle Sinckler talking about 10 man rugby, in my opinion you don't win modern rugby matches or world cups playing that way.
