Statistical likelihood of goals scored based on the quality of chances created and shots.
Basically a big stats nerd fest where they've gone over thousand of goals scored or not scored and calculated the likelihood of players scoring from that position.

isn't it just easier to count the number of actual goals scored, or is this another fabricated table that the RS can be top of?

They have a database of games, according to shots taken, where on the field players have had the ball, or a penalty kick being awarded will greatly raise it. It's supposed to average out where these data points or ball possessions result in goals...

I don't know. Some people swear by it, I still struggle to analyze it and really understand it. I've watched games where I don't find the xg to be accurate but for the most part it is good. However I've found when these tools are used to predict the future they're unreliable.

I can remember Brazil being forecasted as a 70% favorite or so when Germany destroyed them in the 2014 semi's. I don't know anyone who thought that team minus Neymar was that much of an overwhelming favorite in that game. I do usually pull for Germany due to ancestry and the Americans being [Poor language removed], so i could have had my own bias as well. But that just always stuck with me as something that was way off, and it was shown to be.

The only way it really becomes useful is as a rolling average of a lot of matches basically. Trying to predict something like a World Cup on xG is kind of silly.

Trying to predict the World Cup on anything is pretty silly. Wasn't an octopus better than people?
