Those things are all factors, what I'm saying is they are insignificant compared to the most important factor, which is playing talent and that is where the luck comes in.
Sorry, we'll have to agree to disagree on that. We've consistently improved low draft picks and rookie picks to competent players who fit our system and buy in totally. That's not luck.
Drafting players is a lottery, no matter how much science and preparation clubs put in. If you are lucky enough to assemble a list of talented players who are mentally and physically equipped for success then all of a sudden all of the factors you describe are seen as being pure genius, when in reality the margin between the best and worst club in those areas in very small.
Agree to some extent. Higher picks have a better chance of success but the majority still fail. I'd argue it therefore becomes more about culture, management and system. In terms of raw talent spread across clubs it would be fairly random and thus fairly even. So the intangible and tangible decisions and strategies a club makes to maximise and develop talent become even more important.
There is no better example of this than RFC - talent pool between 2016-2017 similar, results completely different.
