There's an interesting stat that I like to look at in Football called xG. It's essentially a metric of expected goals based on all the shots that have been taken, and factors in things like where the shot was taken etc... Yet I've always thought that it was an imperfect metric as it didn't take into account things like opportunity cost of shooting when you could have passed to someone with a higher xG, or even the position of all the defenders / keeper when you're shooting. It would be cool if we could use a system like this to better understand the xG based on all of those factors and more. Basically, for any given position where we take the entire field and players even, into account, what is the actual xG.
