This makes complete sense to me, and I totally agree 👍, coaching it not just about having the right players, it's also about building a winning strategy into every of those players, and this can only be achieved in the training pitch just as you have mentioned.

Different clubs and coaches have train their players in different ways and strategies, and one job of a coach is to find the right strategy that not only works, but also is easily learnable by both the players that's been there before, and those that are coming in.

And we can use money as a good example, It doesnt always matter how much money that enters a person's hands, what usually matters is what the person used the money for, that alone will determine whether more money will keep coming in passively or not. And this simply means that, it's one thing to have players that are potentially good, but training them properly is what turns that potential to reality.
