What really impressed me re Test I and answered my pre-game question - what has the Wallaby coaching team learnt since June 2016's disaster if anything? - was the obvious calibre of improved technical coaching in virtually all aspects of Wallaby play bar kicking from hand (which apparently is an impossible skill to teach Australia's elite rugby players) and line-out.
There was a clear, consistent game plan that (largely) worked - tick
Defensive structures, technique, offensive defence, intensity of application across whole squad - tick
Technical skills in ruck work re effective clean-out, use of pods, good turnover rate, etc - tick
Low error rate in passing accuracy and speed, knock ons, dropped balls - tick
Coherence and discipline of 'total attack' (vs our classic 'one outs' reliance on a few stars and the rest a mess) - tick
Tolerable rate of penalties yielded - tick
Capability to play at high intensity for 80+ minutes - tick
Scrum - solid to outstanding - tick
Cheika cutting the counter-productive hyper-emoting, ref-blaming and seeming calmer (ie, way better for balanced team temperament) - tick
If the above Wallaby coaching capability as rendered in the team's performance is broadly sustained in Tests II and III we will start to look like a consistent team that can (a) consolidate our wider rugby fan base's desire in buying Test tickets and (b) move towards being credible for a chance at a BC win in 2018 and (c) ditto credible for a solid RWC '19 performance.
