But then we're talking about different things. What I has said originally is that non-trolls know that not every player is going to be graded the same, so Kawhi getting 12 points will be graded much more harshly than Bertans getting the same total. I do think everyone knows that to at least some extent.
What I was talking about in this thread was whether an average night would be a C, B, A or somewhere in between. As I said, I curve to a B. But if someone curves to a C, then it's not like they're wrong. And if they do curve to a C, that would make A's much harder to get and C-minuses to Fs easier. If we all just agreed one way or the other, then the grades would probably have less variance and controversy.
You're right though, that there will always be differences in standards. For me, Simmons scoring a handful of points efficiently and not hurting the team on D might warrant a B-minus. But for guys who actually think Jonathon is a good player, then the piss-poor defense he played in the last game might really cost him.
