Cheika is changing the game plan, particularly around the breakdown in almost every game - as the Ruck Stats show.
England won the 3 tests in the June tests with much less possession than the Wallabies but there were still some high ruck involvements.
In the Test against the Pumas, both teams were standing off opposition rucks a lot more than we've seen in other Tests this year.
Is it part of developing a game plan for when the Wallkabies are without Pocock & Gill and more in line with the way the game is being refereed?
IMO that would be a shame for the game, as one attraction is the physical battle for the ball which differentiates Rugby from other ball games.
Maybe they're just playing different game plans against different opposition based upon what they expect to face? Maybe it is not "developing" but targeted at different teams? No matter how expert many of us think we are , maybe there is a bit more going on than we think? We look at what the ABs forwards do, and it's easy to apply the logic that ours should be more like theirs, but maybe a pragmatic approach is taken, conceding that we have a slightly different basic level of skill and fitness to some of theirs. I'm more inclined to think players are doing what they do, or don't do under a plan, rather than just shirking the load. This is not to say the plan is always right, but it looks to me like they're mixing it up a bit. All just spitballing here, not having a go at you.
One thing which interests me is the bolded bit. England have conceded they don't feel they need a "fetcher" per se and played 3 munters in the back row against us, with good effect. Pocock is being more effectively nullified these days. The way Barnes reffed the game really took Pocock out of the equation, apart from slowing the ball a bit. Can he adapt? Sure, he's good enough. McCaw did all the time, which is why he had such longevity at a high level. I think the archetypal fetcher, while likely to always have some impact, is less likely to dominate these days. I think the players who are that archetype can easily play a different role, however.
