Kinda feel like all the guys will improve, of coarse I got the Orange glasses on. Only real evals that count are the grades the Coaching staff deliver. They probably are paid more and know better what they want and expect.

I’d like to know how their grade is arrived at no doubt but he clearly had more good plays than bad ones so you can’t be serious when you say otherwise. He did complete 19/31 passes keep in mind

I understand what you say. However, I was thinking back over the first half at the break and it seemed to me that JG, with his poor passing, ended nearly every possession with HIS bad throws. What was it, 1 for something like 12 on third down?? That tells me he was subpar as usual....

They will. But improvement within a season is usually inversely proportionate to the amount of experience and development a guy has. I think we can probably expect Keyton and the Fr WR's to improve more than Palmer, Jones, and Johnson (who all played very well IMO). Baron is likely to improve more than Johnson or Bennett (who also played well).

Spraggins got some PT. That experience offers a greater opportunity for improvement than Kennedy or Smith who are much closer to their potential as college OL's.

PFF has 600 full and part time employees it is a money making group and very subjective 600 different views. Does the guy grading your QB give said QB benefit of doubt? Was he a fan of this team growing up? it goes on and on. Its a measurable but it is fraught with all kinds of chances for subjectivity. Think about it there could be over 50 games (100 teams) on a weekend. You have at least 40 X 2=80 participants per game. So across the country you are doing individual grading 4000+ players individually by 600 people with different ways of grading. That's one person grading or keeping his eyes on 7 players every play and charting it. I just dont put much into these measurable, their 600 different views from some who where probably drinking watching the games etc...I'm sure their not i the same roombeing monitored. There are so many ppl involved that I think it loses credibility. Think about it former Gator Chris Collinsworth owns it and its located in B1G country Ohio.

Geez, nothing like a good conspiracy theory in the morning. I wonder if space force has determined if the Earth is round or flat yet.

He made some good plays but more bad plays that cost us from blowing out a team vs. having to recover a fumble to preserve a win. Subpar Qb play. BTW it was more than a few bad plays. Look how many inaccurate throws made JG had made when it was only 14-7. Who created this rating chart. All evaluations regardless of who does it can be subject to bias or unintentional inaccuracy.

As can a poster's view of a player's performance.

no doubt he was awful on 3rd down but PFF grades 1st and 2nd downs as well as they should. He was really really good on those downs so it equals out to a solid grade

WHAT WE DO
The PFF grading system evaluates every player on every play during a football game. We believe that #EveryPlayCounts and that attention to detail provides insights and data that cannot be found anywhere else. The grading system was founded on the principle of grading “production” rather than traits or measurables, but perhaps a better way to describe it is a player’s “contribution to production” on a given play.

Did the quarterback make a great throw, but it was dropped? The quarterback contributed to positive production and will receive a positive grade for that effort, even though the receiver let him down, earning a negative grade along the way.

The benefits of this style of grading are numerous. Taking every play into consideration allows for a larger sample size of data to tell the proper story rather than just a highlight reel of plays that we tend to remember, for better or worse. We also work to eliminate bias by not caring about the level of player who is being graded, so whether it’s the best tackle in the league missing a block or one of the worst, the same grade is given. Preconceived level of ability has no impact on the grading system. This style has worked well in unlocking undervalued gems through the years, while also not being swayed by player hype if it is undeserved.

THE GRADING SCALE
Each player is given a grade of -2 to +2 in 0.5 increments on a given play with 0 generally being the average or “expected” grade. There are a few exceptions as each position group has different rules, but those are the basics. The zero grade is important as most plays feature many players doing their job at a reasonable, or expected, level, so not every player on every play needs to earn a positive or a negative.

At one end of the scale you have a catastrophic game-ending interception or pick-six from a quarterback, and at the other a perfect deep bomb into a tight window in a critical game situation.

Screenshot-4601.png

Each position has its own grading rubric so our analysts know how to put a grade on the various expectations for a quarterback on a 10-yard pass beyond the sticks or what the range of grades might look like for a frontside offensive tackle down blocking on a “power” play.

There is then an adjustment made to the “raw” grades to adjust for what the player is “expected” to earn given his situation on the field. For instance, a player’s grade may be adjusted down slightly if he plays in a situation that is historically more favorable while a player in more unfavorable circumstances may get an adjustment the other way. We collect over 200 fields of data on each play, and that data helps to determine what the baseline, or expectation, is for each player on every play.

Each grade goes into a specific “facet” of play in order to properly assess each player’s skillset. The facets include passing, rushing, receiving, pass blocking, run blocking, pass-rushing, run defense and coverage. Special teamers also have their own facets of kicking, punting, returning and general special teams play. Facets are important in order to have a clear view of where a player’s strengths and weaknesses lie.

A collection of grading examples across all facets of play is included on this page.

WHO IS DOING THE GRADING?
PFF employs over 600 full or part-time analysts, but less than 10% of analysts are trained to the level that they can grade plays. Only the top two to three percent of analysts are on the team of “senior analysts” in charge of finalizing each grade after review. Our graders have been training for months, and sometimes years, in order to learn, understand and show mastery of our process that includes our 300-page training manual and video playbook. We have analysts from all walks of life, including former players, coaches and scouts. We don’t care if you played.

Each grade is reviewed at least once, and usually multiple times, using every camera angle available, including All-22 coaches’ tape.

YOU DON’T KNOW THE PLAY CALL?
We are certainly not in the huddle, but we are grading what a player attempts to do on a given play. While football is extremely nuanced regarding the preparation and adjustments that go into each play call, once the ball is snapped, most players are clear in what they’re trying to accomplish on each play, and we evaluate accordingly. Of course, there are always some gray areas in football. Plays in which there is a clear question mark regarding assignment, we can defer to a “0” grade and not guess as to which player is right or wrong. These plays are few and far between and since we are grading every snap, missing out on a handful throughout the year should not affect player evaluations. Examples of potential gray areas include coverage busts, quarterback/wide receiver miscommunications and missed blocking assignments.

CONVERTING THE GRADES
The plus-minus grades are then converted to a 0-100 scale at the game and season level. This makes it easier to compare players across positions relative to their peers, though it doesn’t account for positional value, i.e. which positions are most valuable when trying to predict wins.

Great info, thank you.

Banks @ 47.7? I get he had the penalties (the helmet being really dumb), but 47.7? Really? Who did this rating?

He got pulled at one point for being horrible in coverage, lateral quickness and stupid penalties, i think its about right, doesnt mean it cant be better down the road, but for game one he was not playing well, at all

Ok, let's assume he was as horrible as you say, aside from the penalties, how does Crouch rate a 59? Banks played much better than Crouch, especially in coverage.

The grade scale is -2 to +2 and I am sure those penalties got -1 or worse grades. Crouch, who I thought was awful, likely didn’t have any really bad play grades

You are stuck in the 90s

Any road SEC win in this current age of vol football is a good day

A win is better than a loss but I’m evaluating performances vs. the level we need to be competitive at
against the Florida’s, Alabama’s and Georgia’s. Isn’t that what 99% of Vol fans are rooting for?

Tyler Baron had a low rating but he made at least 2 or 3 excellent plays. I wonder what he did on the other snaps to get the low rating?

So...... Latrell Bumpus played both ways? And Warren Burrell played?

Looks like they need to work on roster and numbers first maybe, before grading.

We are getting closer to those guys but we can’t skip over steps. We aren’t on their level yet until we win 90% against the rest which we haven’t done yet.


I’d be absolutely jumping for joy to go 7-3 and lose to all 3 of those teams this year
