As a Canadian who is also a Wallabies fan I feel for you guys. We used to be able to win the occasional game against the likes of France or Wales, but it has been a slow decline to the point that we are losing to Uruguay and Brazil. Along the way people blamed selection, the coaches, sevens rugby etc. All of these things on the national side were manipulated every which way, but the reality is that the foundation of the sport here is exceptionally weak and the grassroots is diminished. It sounds like the same thing has happened in Australia and now it is showing up at the top.
It isn't the fault of any individual player on the side or the coach, the country as a whole just isn't good enough. How many Wallabies would start on the All Blacks? Probably Pocock, maybe Folau. Genia, Hooper and Coleman are possibly subs. Props I don't know. That's it. How can you beat a team when they have better players, by far, at at least 13 of 15 positions?
Foley isn't great, but neither is any prospective replacement for him (Quade is a joke), Phipps, Tui, Korobiete, Robertson or any of the other players that are maligned on this forum.
Robertson - clearly too small
Hodge - jack of all trades, master of none
Foley - a 10 that can't kick
Beale - high risk, can't tackle
Korobiete - Fast. That's about it.
Folau - Can't kick
Hooper and Pocock - two best players play the same position
Second lock - not nearly good enough
8 Man and 6: They don't have any!
Tui - Good runs, not good enough at anything else at this point, would be eons away from a jersey in black.
Phipps - Would be the ABs 10th 9
TPN - No stamina whatsoever
Rob Simmons - Again, ABs #15 lock option, South Africa the same
DHP - Solid fullback, no X factor
The ABs are fielding absolute studs at every position. The Wallabies are putting out inherently flawed players, with only a few exceptions. It isn't the fault of the players that they are the best you have. Cheika isn't perfect, nor is Larkham, but I don't think you'd see Steve Hansen leading the Wallabies to a Bledisloe if you swapped coaches.
It all starts at the bottom and the Wallabies aren't good enough because rugby in Australia is moribund. The Super Rugby teams reflect the state of the sport and for the most part they are mediocre. You can't blame Foley or Cheika for the state of the sport, these types of people are the SOLUTION to the problem, not the CAUSE. The players, for the most part, play hard rugby. When you get blown out and are badly overmatched it is hard to keep the same level of intensity up. Yes they ought to, Pocock did, but I've never seen it where a team gets beat by 40 points and there aren't some players that are discouraged or letting up. If the ABs got annihilated a few games in a row even they'd be acting the same. Losing breeds losing.
Anyways just a rant to say that you can shuffle the deck however you like but you aren't going to win a hand if your deck is stacked with twos and your opponent's is all aces.
