I would say the first step towards solving the problem is accepting that changing a couple of positions isn’t going to improve the Wallabies. If there were better 10s than Foley they’d be in the side, if there was a better backrow combination we’d have it in place.
Ok, to reply to your question how this logic is flawed.
Solving a Problem - w/ Up The Guts
Step 1: Accept that changing a couple of positions isn't going to change the outcome (improve Wallabies).
*********
It would be reasonable to deduct that this formula suggests that whatever the selection process, the outcome will be the same, so we should not bother changing players.
In any equation, mathematical, or otherwise any small adjustment to the first half of the sequence will radically change the second half of the sequence and as such the equation is different.
The first half of the sequence in this situation is preparation, tactics & selection. While the selection is not the is
not the only ingredient here, we can all agree that the "cattle" that are put out have a significant amount of impact on the outcome of the event.
Changing even 2/15 players from the XV is a 13.3% change of combination (left side sequence) that could be reasonably expected to impact the right side of the equation (outcome) with some level of variance (either positive or negative). This does not even factor in the individual changes of combination that would be a much higher %.
Ie; if To'omua started at 10 he would have a direct and new combination with Genia & Kurtley that creates even more change than the individual selection % (of 13.3) suggests. These are human beings acting collaboratively, the network effect that changes the functionality of the chain (in this case it would be a backline).
To suggest that no difference in selection (not to mention tactics or other factors of preparation) could ever alter the right side of the sequence (the equation) is meek and defeatist.
Also note, that this is not about changing a few positions and getting the win. It is about changing the mechanics to improve by degrees, that allows us to continue to develop until we get the desired outcome (the win).
We can't be happy with the existing team and process if it is not working, especially when no other selections have been tried. This is
counter-intuitive logic.
We much keep adjusting the
formula until we get the desired result.
That is what all businesses, sports teams, and any collaborative group exercise is attempting to do.
To not adjust and adapt is to plateau, and to plateau is to die. The Wallabies are currently dying if we do not introduce change of process (selection included) to break the circuit and change the equation.
