Why discredit the pff grade?
I believe grades have something to do with:

3) Missed assignments - blocking nobody
4) Missed run blocks


.

Because without knowing the exact Ram Playbook protection Scheme and or/whatever the QB checked into at the LoS when looking at the defense it is IMPOSSIBLE to know which OL are missing assignments in ZBS. There are way too many combinations and adjustment responsibility's to account for. When you add to the equation a late blitz/line shift/stunt by the defense new assignments and special contingencies apply.

On any given blitz/stunt/twist vs a certain variation of a play from whatever formation and protection package call that goes with it, I am indeed contending that PFF does not possibly know the correct blocking assignment responsibilities for the play call. It goes even deeper than that. They can't even possibly know what the QB or center checked the line into at the LoS. Then even further they don't know what the coaches have told them what they do in situational adjustments responsibilities when the defense dials up something exotic.

Here is a running play from the Martz 2000 Playbook. Its is only assigned for a 4-3 without accounting for exotic shift/blitz stunt contingencies. Which like we all know, happen frequently.


If you notice the "Alert is Cal". Which changes the LT assignment on the play entirely. Are you going to seriously going to tell me first that PFF has ever play for every single team with every variations and combination of correct blocking assignment against every possible defense? Second, do they have listening devices to intercept and interpret the "Alert" by the QB at the LoS? This is pretty critical information if you asked me if I was grading a play and was going to assign who exactly missed a given assignment.




I could easily go into more detail, but i do not have the time.
