"Not accounting for dumb/bad luck" or the fluctuations of players' mindset or form throughout a game is what makes it flawed...
and, dare I say it, misses half the point of why we love football.... It ISNT perfect, mistakes are. Made, and THAT'S the beauty of it... You CAN'T, nor should you be able to predict it...
It's trying to take guesswork, opinion and surprise out of the game altogether...
Xg is just a glorified video game stat generator....
Players aren't machines...
Had it been around back then, Xg wouldn't have accounted for Gerrard's slip v Chelsea, or Mendes' dissallowed goal at Old Trafford... Or Trippiers' o.g v Chelsea...
or countless other slips, brainfarts and gaffes down the years that have won or lost titles, let alone games!
At best, it's an after the event 'Woulda Coulda Shoulda' gaming app that becomes infuriating when you look back at 'what you COULD have won!
Bloody X-Box gaming generation ruining REAL football!
Football is the game it is because of ALL ITS IMPERFECTIONS!
Are people still boring on about Xg?
I bet these 10 goals had an Xg below 1
All it means is someone had the ball in a good position to score from.
