ofcourse stats was coming into the game - and the modern game took to it like wildfire - incl the countless other additions the Pro game expanded on.
Just look at the employee list of the big Clubs - like corporations.
I've read Kupers but he's late on this subject such as this of his hence the modern day coachs named.

This below I'm sure you'd find more facinating for its the pioneer long before used in English Div1 pre EPL.

Wow young un's, look up Graham Taylor was a legend back in the day.
Anway as I've mentioned in other discussions when talking top leagues its not like for like - players who have made it (well not all are that great) have the ability been picked for top levels we're talking grass roots up pre Snr's that our system/s, be it not Dutch I'm led to believe but for Burgers name, be it a mix of countless styles has its flaws at the same time.
Too rigid, stifled individual promising young players, possession possession reset reset reset - we do have robots no one can deny this.
We have NO true strikers, regular scorers, 1/2 midfield complete players.
We have imports such as Souttar - whereis more robust tall capable CB's like Souttar made in Oz.
There's plenty chemicals in the chickens eaten today, why haven't we got any monsters

I don't want to hear wait for this next U23 gen, I have heard read of this for 20yrs.
The Japs have left us behind, as some other asian/ME NT's have shown as well.
When I grew up before all this analysis, it was in the Coach's head, their experience, their nouse watching players in varied positions and their ability.
You sure well can tell when someone "has" it or the potential.
Having played Div1 and Rep my Jnr's and mature age Div1 I have watched some very talented individuals that the last 20yrs would have been driven out of the game or had to change their natural game 3fold to stay in the game.
As the winning Argie WC coach said recently and this is due to stats/methodologys imo :
Scaloni: "We are losing the essence of football, and not only at the professional level, but also at the kids’ level"
It is becoming robotic - oh he/she is a hog, you can't be selfish, everyone is a winner at Jnr level, well won't they suffer mental health forging ahead - your gonna cop loss's petal.
You know what the system should be endorsing now is ? encouraging the budding individual to be let loose.
Encouraged how to work with his/her team mates but go for it - this will counter act the robots, they don't know how to deal when "jokers" are released in the pack.
There's the hole to expose.
