There are definitely factors at play that aren't initially knowable from just looking at the tape, but as you stated in your example, you can actually usually tell when there's a miscommunication between the QB and receiver. Broken plays are easy to spot. The WR or QB will usually throw their hands up or look confused, one will usually cop to it. But body language is a very precarious metric to use, so I wouldn't use it as a significant factor in grading a pass. What I would use is the quality/difficulty of the read and throw (which is what PFF does), and you're basically saying it's impossible to grade the quality of a throw. If a QB throws into triple coverage and it's picked off, it's different than a DB making a great read on a ball and coming up with an athletic interception. Aaron Rodgers' interceptions are usually of a different type than Jay Cutler's interceptions, and it's unnecessarily inaccurate to grade them the same. No grading method will ever be complete because the statisticians aren't inside the heads of the QB, WR and coach, but we don't have to just accept all incompletions or interceptions as the same.Why was it over his head though? Did the WR flatten out when the route was to continue upfield? Did an adjustment of the DB change the WR's route between the ball's release point and when it reached where the WR should have been? Did pressure in the pocket or contact initiating with the QB as he's throwing affect the throw? There are too many factors in there to put gradients on the pass beyond it just being an incompletion and, because of that, there's no way to make that into a statistical model.
For example, you see a pass land 5 yards to the left of a guy down the field. Some fictional model has that as a "bad pass" over just an incompletion, so it's -3 over -1 in numbers if you only watch the play. When seeing everyone come back to the line of scrimmage, you see the QB motion to the WR angrily hooking his hand inside seeming like that's the route he should have run. So, it seems the WR ran the route wrong, and, looking back at the play, you see if the WR followed the route the QB motioned at the point of release, he more than likely would have had a catch w/ YAC.
So is it back to -1? Is it now a positive play in the QB's numbers because it was a potential completion (like the potential interception) and the WR gets all the negatives? If the WR ran the route properly, how do you know the DB wouldn't recover and jump/block/disrupt the route? If the cameras don't catch that interaction between the players, you don't even know the WR busted the play &, without knowing the play yourself, you're just taking the QB's reaction as proof he did. And on top of all that, maybe the QB's out of the pocket and throwing to an open spot b/c there's no play to be had b/c the player ran the route wrong (which is still a "bad pass" but done for a specific reason to move on to the next play). Outside of the result of the play being an incomplete pass, everything else is all subjective guesswork on a pass that simply looks bad on the surface.
And that's just the problems in breaking down a "bad incomplete pass" vs an "incomplete pass". It's grading on hypotheticals and/or subjectives (like "interceptable passes" or "bad incomplete pass" ) I have an issue with when it's hard enough to break down, interpret and put numbers to what actually happened on the field. Some things, like incompletions, might have to remain a pretty broad statistic by necessity and breaking them down further more a subject of conversation than something to put into numbers.
A QB should not be given the same grade for this throw
as he is for this "throw"
I actually don't have a big problem with PFF using potential outcomes in their grading. It doesn't matter if a defensive player drops a pass thrown right into his chest, the play was a terrible one that is very often intercepted.
Again, this pass
should not receive a better grade than this pass
Both are flukey plays, but the former was a terrible play from the QB, saved by an anomalous fluke, while the latter was a good play from the QB, ruined by a terrible play from the WR. If we don't factor in potentiality, we would end up giving Peyton a worse grade than the Rams QB, which is patently absurd.


why do people care about these nerd stats. Dweebs still trying to sit at cool table
...but other than that, I have no beef with their grades. I have no beef with their evaluation of arod here. it's consistent with their grading system.
