I will break my post into a two part job for this game and the tour as a whole.
As I posted before the game some time earlier this week, I expected the Scot forwards would dominate as the second row is far superior to the Wallabies, and I'd suggest that even the addition of a single Coleman figure would not change the fact that whoever has partnered him has been for most of the year, who ever it has been, largely a passenger. That is not to say the loss of him in the second row was not brutally exposed. I also thought the backrow as for most of this year is grossly underwhelming in actual power in contact, as opposed to work rate which doesn't actually measure anything about effectiveness. McMahon has some brilliant moments of ball in hand contact work but some fairly ineffectual moments as well, the same in defence. That said he is the only one that has actual in tight power in contact, Hanigan up to this point showed zero, plenty of workrate, lots, huge workrate, no effect, McCalman, slightly better, but as in every other test he has played against top opposition pretty much the same as Hanigan. Hooper massive workrate, tops the tackle count, metres run and most penalties and yellow cards. Am I surprised that they were totally outplayed by Scotland, who have as I said a very good pack, no, it was predictable when selecting such an unbalanced side with no real go forward. and one of the best tight ball runners in the side sitting on the bench in TPN. The pack also totally lacked any ability to combat the mauling of the Scots who I think successively drove for about 50M in this game (total).
Now even before the obvious excuse of the Red card to Kepu the Wallabies were struggling with the other point I mentioned through the week, the defensive structure. It doesn't matter who is selected in the side or where players are positioned, the line itself, the structure is so poor that all that is needed to generate an overlap is to go wide one way then swing back quickly cutting the midfield entirely and the Scots had innumerable overlaps, easily generated without even needing significant forward momentum at the first phase. They certainly didn't need multiple phases to catch the structure out. Some poor handling which the Scots didn't display against the ABs saved the Wallabies from a worse scoreline.
Kepu was slightly unlikely in his contact with the Scotish 7 in that the Scot was on his way down when Kepu came in, but slightly unlucky is as generous as I can be, it was reckless and even on first real time viewing I called it a red.
The Wallabies as they were against England will say they were in this and point to three tries and near parity on the scoreboard to near the end, they can kid themselves. They were never really in the game, they were outclassed totally, and the biggest part still comes back to my second point about defensive structure. From the Tahs to the Wallabies Grey's defensive work(structure and actual team execution of the plan) has been terrible since 2016. That's two sides with terrible outcomes. There is nowhere to hide from that.
