I come here to discuss my team.
Unfortunately, it seems that too many people look at a stat like xgf as proof that we could have, or even should have, won; so we're a good team, end of conversation.
Or: we should have won, but didn't, so it must be the fault of the refs, or scheduling, or injuries, or 'the trap' (as if that was an illegal strategy), or a conspiracy.
I look at a stat like xgf, compare it to actual results, and wonder what the difference represents: better or worse coaching, luck, one or more shortcomings in the model, et cetera.
