There s a reason a number of BYU players lead PFF at about every spot in 2020. Its easier to execute correctly against your comp when they arent good. Criddle has the main PFF guy on his show every week. Might be worth a listen for you sometime to understand how they score based on how one person basically is scoring if you did what you should have. A QB for instance gets a positive for incompletions if the receiver should have caught a ball. The analyst is the one who determines this. John Beck who probably benefited a lot from Zach's glossy PFF doesnt think its super useful.

One other thing he has mentioned, when they are grading there is some guesswork involved. If a receiver and quarterback mix up signals and they dont know who s at fault, it does skew the numbers.
