xG is used by football clubs and has directly been mentioned by Klopp, Tuchel & other managers, but I expect you know best.
I get when you get to a certain age it might get annoying to see progress made in data analysis that you can't quite grasp, but that doesn't mean the analysis is wrong, just your perception of it.
I use data and analysis on a daily basis, but you see - the data and analysis is built on facts and realities, so its meaningful and actually drives development.
I have spent my who professional life adapting to change, and embracing new tech and new ways of doing things - I work in telecomms you silly person, and I'm still doing it in my 60s.
Xg is a fallacious, load of codswallop driven by human failings, guesswork and a desire to make a sport into a science, which they will never be, as long as they are played by humans.
But the gullible will believe what they are told
"Look at the King! Look at the the King! Look at the King, the King, the King!
The King is in the all together
But all together the all together
He's all together as naked as the day that he was born.
The King is in the all together
But all together the all together
It's all together the very least the King has ever worn."
