re: PFF on the Davenport trade

The problem with PFF is they don't know what someone's assignment was. They can guess but they don't really know.

A quarter can slide the protection and one of the lineman doesn't do it and another lineman can get a bad grade on that play because it wasn't his fault.

i mean, this is an inherent problem with any game/film analysis

Teams use that information from the combine and put it against the tape.

The same way they'll take player grades and put it against the tape.

do you think that NFL teams magically have the information that PFF doesn't?

obviously they are in the same boat, thus, if we expand your argument, all evaluations of film are flawed in the same way

so what, exactly, is the criticism given that picture?

i'm not saying PFF is god, but the alleged issues you point out apply across the board, so it's an analytical constant
