All stats are useless. They are just interesting, that's it. Not indicative of anything beyond being a series of individually collected digits, but consistently misinterpreted as predictors. Fantasy sports have fetishized stats beyond their actual relevance.
Per example, LA GM Blake recently stated that the Kings need to lessen the gap between goals allowed and expected goals against - instead of saying that they need to play better defense. Stats are products of play, not anticipatory. Folks just don't see that their use is a mathematical fallacy.
