Yet quantifying that has yet to bear out that it actually results in goals against more regularly.
Faceoffs are one part of hockey that I am absolutely convinced that the analytics community has wrong. I'm not sure I'm eloquent enough to explain my thoughts on it.
I think what it comes down to is that on a large enough time scale (say over the course of a season)......sure, faceoffs effect could/should even out.
But I think it underplays situations like:
1a.) A faceoff in the defensive zone that immediately turns into a GA/GWGA.
1b.) A faceoff loss in the defensive zone that is never cleared and turns into a GA/GWGA.
2.) An opening faceoff in OT where the losing team basically never sees the puck
There's gotta be a way to separate neutral zone faceoff effects from D-zone faceoff effects.
