ok but I think the point I was trying to make (I think) was that single game usage of xGF% or CF% or whatever it is DOESN'T represent that a guy is "on a heater"
just like being +4 in a game doesn't mean a player was defensively sound of offensively contributing
I've talked to Rob Vollman about this a number of times and asked him if he would put more value in years worth of +/- or days/weeks worth of corsi/xGF stats and he said years of +/- without skipping a beat.
THAT is my primary beef with the way "analytics" are used.
They have simply replaced all the old tropes that people used to use to make arguments without nuance. They carry a certain cache with them so that people can toss out a bar graph and say "There the nuance has been reliably done for me so now my argument is valid!" but as
@Statto so elequently stated (Statt-ed?) single stats do not tell an entire story and more context should always be welcomed and is almost always available.
An obnoxious anecdote... a colleague asked me about tracking physicality in a player's season and I offhandedly started giving some ideas before I immediately realized the player in question may be playing way more minutes this season than in previous seasons and that to more accurately track the progress in their game a look at the "per 60" stats would offer up a far more accurate representation... and that was just off the top of my head and stats that I'm aware of and fairly conversant in.
Honestly I'm not even sure my point or if we're disagreeing I;m just in a mood to type stuff before the game tonight so feel free to ignore all of this.
