I can't fault much, if any, of what you say here.
I have a couple of comments though about the way England has been trying to play
1. I think what the RFU and to a certain extent SL and his backroom staff have failed to do here is to understand what it takes to play this type of game. You have to commit to it fully; not just in how you play on the field, but in training, and attitude and selection policies too. You also need players that have great ball skills all across the park as well being good at their core jobs. Can any England fans imagine Jamie George or Luke Cowan or Dylan Hartley scoring the kinds of tries or having the ball skills that Dane Coles does? Are there any locks or loose forwards in this England team with the ball handling skills of Whitelock, or Retallick or Keiran Read or Michael Hooper. Playing the way the All Blacks and the Wallabies play is risky, and we come unstuck doing it sometimes, but its no good hedging your bets and trying to play this way in a half-arsed fashion; you either commit to it, or stick to what you know. IMO, Australia out-skilled England on the weekend... they simply do not have the skills to play the game they were trying to play at this level. Perhaps they should have gone to Plan B and played the territory game. They might not have won, but IMO they may have had a better chance.
3. It may well be that any serious attempt to get England consistently playing the type of rugby we play, AND being successful at it, is doomed to failure because you simply don't have the domestic structure in place or the grounding in that type of rugby from the bottom of the game up. It is going to be very difficult to change the style at the top level when the players don't play that way at other times. The attitude to wanting to play that style begins from the first day that kids pick up an odd-shaped ball, and in progresses up through minis and Ripper Rugby into the college schoolboy game and on upwards Anyone watching Landrover 1stXV Rugby for the past few seasons in New Zealand will be amazed at the sheer skills of these schoolboy players.
That is just my ten cents worth anyway...
Yep, tired of this "I want us to play like the All Blacks" mentality some England fans have, it's just not realistic, it's a completely different rugby culture. Unfortunately Lancaster himself was one these people.
