Of course that is generally true. One weird year Huddersfield got promoted with a minus goal difference.I don’t follow stats and xG goes straight over my head but I do look at goal difference.
Since we came back up to the championship, bar two seasons with AN, our GD has been 0 or minus.
Generally, the worse your GD is, the lower in the table you finish.
At present, our GD is saying mid table again.
Once remember the Lashers getting relegated with a goal difference of minus 1 which would have been in about 1978
