for me, it’s pretty confusing in quite a few instances, but, just to give an example: if the striker shoots and the keeper saves it, but the striker taps in the rebound, how is xG counted? is it counted twice or just once? or, what if neither shot goes in?
Okay, but goalscoring is not just about finishing, it’s about getting yourself into dangerous positions to shoot from. xG is not the be all and end all, but it tells you how effective a player is when it comes to finishing chances from given positions. Say you had 2 sons, both with 111 goals in 280 matches, but one had an xG of 130 and the other of 90, you would clearly be putting your money on the latter as that demonstrates they are more clinical.
