One of the common discussions you’ll see here at BSB is the discussion about luck masking poor play, and poor luck masking good play. Generally speaking, teams that have a PDO (SV%+SH%) over 100, then the team is lucky. It’s a general rule, as skilled teams are generally over 100, especially teams with elite goaltending. There’s credence to the “create your own luck” argument, but abnormally high/low PDOs generally balance out.
That’s why xGF% is used to determine how well a team is actually playing. It takes the quality and quantity of shots taken/allowed and turns it into a stat that is usable.
