#9 in pff offensive line rankings through 3 games.
I have a hard time with those PFF rankings. Brendel is constantly pushed into the backfield and he apparently gave up no pressures last game.
It has to be highly subjective just based on its nature...
I researched this one, this is what you are looking at per PFF.
400-600 full time/part time analyst that prep film and organize it for the Graders. Lord knows how long this takes...they say they have access to the bulk feed. That means all 12 to 24 cameras deployed. So it's not just watching the game 50 times to get all the players. This is worked down and isolated by the 400-600 crew.
They have 30 people that are "trained" to grade players.
Since we have no idea how long it takes to build isolated film, let's just look at the raw numbers We will go with the lowest amount on everything to build a minimum.
130-155 snaps per game so lets use 130
130 snaps x 22 players per play= 2,860 grades per game
NFL plays last between 4-7 seconds on average...lets use 5 seconds
2,860 grades per game x 5 seconds of average film= 3 hours, 58 minutes, 20 seconds of raw play time footage.
Raw play time x 16 games a week = 68 hours, 33 minutes, 22 seconds.
So our 30 graders, each have 2 hours and 7 mins of raw play time footage.
That again is after we assume that the army of 400-600 people are clipping each play down for each player in isolation from snap to whistle and provide snap data...ie...it was 3rd down and 12 yards to go....
Here is what don't know, but can likely guess on.... That that 2 hours and 7m can be multiple that by 12 to 24 camera angles Let's keep that light and go 12 cameras.. each Grader would have access to 152 hours, and 28 minutes of truncated tape to look at....let's assume half of that or less is useful.
Raw Play Time x 6 camera angles= 12 hours and 42 minutes of useful material if they only watch it ONE TIME AT FULL speed.
We know they are not watching each play 6 times from every angle at full speed....highly unlikely they are having those dudes pull a 13 hour over night shift to get this out Monday Morning.
Ok, let's say its an 8 hour shift...and there is NO BS, no team calls, no chatting, no "hey mike holy hell look at this", you can get 1 full speed view at 3 angles per play for 3.77 total views.
We know that is not really right, I am sure they are also cross referencing the data " is that a 4 yard carry or a 6 yard carry." I would assume that is done in mass by the 400-600 crew, but our grader still has to reference it...and ding ding ding...log it...they have to type something...that takes time.
What about slow motion plays, pee breaks, lunch hour..... They doing this 8 hour shift with the same attention of a Heart Surgeon? Of course not...like the rest of us you are lucky if you get 6-7 work hours out of a 8 hours shift....
What we are left with is they can't watch every play and also give it the attention it deserves.
We still have no idea how much time goes into prep work, nor quality control. Who is grading the graders and when? Before its published? I doubt it....
There is no way they could do the job we want them to do and still get it out Monday Morning....
So why is Brendell still rated so high? It is likely the "graders" care less and spend less time watching him season to season as the average fan. The Grader in theory might have that 120 snaps x 5 second with all 12 angles (2 hours) on the play...but he is not watching and re watching that 2 hours of tape on that one player...and lord knows ...he might not even have Brendel. next week...he might not even be building a week after week after week impression of Brendel like a fan would.
