    The alternative Championship which has Bristol City in relegation battle, Nottingham Forest in mid-table and Stoke City in promotion race
    There are some big mover in the expected standings for England's second tier

    Anyone who has watched any amount of football from the second-tier can tell you that the gap between each side is as tight as any league in the world.
    With that in mind, the best from the rest are often defined by those that can take their chances in key moments of the game.

    This season, West Brom lead the way at the top, whilst Stoke City prop up the table in 24th place. Nathan Jones' side, however, haven't always looked like a side you would expect to be marooned at the bottom of the second tier.

    In fact, outside of both 18-yard boxes, the Potters play some decent football but lack a killer edge in attack and defence.

    That has given Jones the constant belief, which he has relayed on a number of occasions, that with time, his side will begin to climb the table as they bid to get on the right side of the small margins costing his team.

    Similarly, at the other end of the table, missed chances have cost Leeds United the chance to be clear leaders of the division.

    Marcelo Bielsa has been left pulling out what if left of his hair by his side's inability to make the most of their clear dominance in the way of goals, which was perfectly highlighted by their recent 1-1 draw with Derby County.

    To get a greater understanding of how clubs are performing, the ‘expected goals’ (xG) metric allows us to decide whether a team isn't performing, or whether luck isn't on their side.

    Expected goals assesses every chance in a game, determining the probability for which a player should score. Thanks to the excellent experimental361.com , run by Ben Mayhew , here's a look at how the Championship table could have shaped up.

    As the below data displays, Bristol City have huely outperformed their xG and the fear will be that slowly the Robins should revert to the mean as there's only so long they can buck the trend of what they should be scoring against what they are.

    Ben is clearly a Gashead with nothing better to do in life. Funny how the perceived 'bigger' teams always do well in these predictions....... Why is our probability of scoring so low? Before the last game we had scored the most away goals in the division, so why is our probability suddenly so low?

    this table is dead in the water as soon as the first goal or missed chance is recorded … everything after then becomes … a different path!
    It is like saying "we could have scored /won by 3 or 4 today" not nil nil ............had the first goal gone in then the whole pattern of play that follows has no or infintesibly little bearing on what happens next! …. you might be saying "after that first goal I thought we might have won 3 or 4 nil not lost 2-1!"

    Ratings change over the season - The way a team attacks alters. Attacking through certain zones and shooting alters probability. Teams outperform and underperform their ratings. Afobes injury affects Citys rating. City's probability of scoring is now lower with Afobes injury although v his historical performance he was outperforming norms. His conversion rate of chances was very very high but unlikely to remain at that level. Diedihious rating are lower = The teams are lower.

    The ratings are free from bias. Bigger teams generally will have better ratings - Money. Non big Bournemouths stats were top and second attack and defence = Promotion.

    So what's his expected goals metric actually based on??
    What makes a particular zone better than another
    Does it take into account individual player preference - e.g. Jarred Bowen cutting in from the right onto his left foot would make that zone more important to Hull than say Bristol City

    Afobe has been the chances he had and the chances he scored. He has scored significantly over norms from the areas the chances were created in.

    You are already providing the explanation there. Central areas have higher xG ratings and there then are differences between far and from post and angles. Teams xG can then alter v player ability. Players ability is considered. Crossing to dwarves would result in a low xG.

    Not all xG models are the same as some will discount penalties, free kicks and exceptional goals as these can skew the data.

    In many respects its not that much different to thinking he should score or will if he keeps having a go. Data normally; confirms it, however there are times that data will identify bias in thinking e.g. Many people don't understand how ineffectual crossing into the can be even to an adept forward/forwards.

    The article in the opening post is a little uneven because xG should be combined with other ratings (defending etc). The combined e rating is more reliable.

    really!
    every throw in ..., goal kick …. corner ….. missed shot … goal scored … foul … alters what comes next and playing with dwarf's would only result in more nutmegs by the player darting between the legs of a 6' 6" defender whether he was centre xg off centre xg whatever ……………….. load of kiwi fruit
