Thats not exactly what I'm saying.
I've seen guys who did almost nothing in a game get 80 grades.
PFF does not, even by your admission, give grade bumps based on context. Context matters in sports! It matters a lot.
Thats why you have some fans who think of NBA player Robert Horry as some great player. He wasnt. He was a role player who hit a few big shots and some people think he is HOF worthy.
Simmons made a handful of ordinary big plays (his tackle one on one in the hole on Henry) and had a big interception.
I've seen this a lot from PFF so I take them with a massive grain of salt. I'm not saying to fully disregard, but they aren't perfect at all.
Here's the thing though, and we already covered this.
The issue is with with the "I've seen guys" part. Because we all watch football the same way, as a form of entertainment. So we are watching where the ball is most of the time.
There 130 total snaps in the game and on each one 11 players had a job to do. That's 1450 individual tasks performed in the game and not one of us noticed more than probably 100. Let's be generous and say 150 tops. At most we saw 10% of the action and our judgement on whether someone was good or bad comes from their plays within that 10%.
Now, if you want to say that PFF is flawed because of method, quality etc then fair enough. I don't know enough to make that argument. While I understand their -2 to +2 grading system and can see it's technical merits I don't necessarily agree with it's lack of weighting.
The one thing I can never get behind is the casual fan saying "This grade does not match up to my eye test". Well, frankly, all our eyes aren't worth anything combined.
I'm never going to get on board with the idea that 3 trained analysts watching each play by each player separately is less accurate than the max 150 individual plays we see while talking, drinking, eating, tweeting and posting on ASFN.
