There are times where PFF grading scale makes no sense and that would be the curious case of Jermey Zuttah.. Zuttah spent 6 of the first 8 games looking completely lost at times. When the oline was in shambles starting Hurst, Jensen and Zuttah there was plenty of times where neither Zuttah or Jensen touched a DL or LB , but hey if Zuttah managed to get a positive grade, I guess he blocked the air well.
During multiple games we've seen Zuttah drive so far back off the ball that Flacco was stepped on by Zuttah.
I'm sure he's had some good moments in there, but a consistently high level all year is an overstatement imo.
If Zuttah's play at oline is consistently high, then players that have performed consistently high : T.Young, J.Smith, Jernigan, Wagner must be at an All Pro level then.
You're right "consistently high" was an exaggeration. But the PFF grades for for all of Zuttahs games are a pretty accurate representation of his performance. The first thing is that the grades which I referenced are not cumulative. They are based on a players performance for that particular game. He definitely had a rough four games at the beginning of the year, and its not an excuse, but as you mentioned above, the Oline was a revolving door during the first half of the year. There are going to be mishaps when an OL hasn't had time to gel. Not to mention the fact that the replacement players are going to be a down grade from the starters, which also effects OL performances. The grades aren't based on just a handful of plays "Zuttah or Jensen touched a DL or LB , but hey if Zuttah managed to get a positive grade, I guess he blocked the air well". Every single play that a player is in the game for is graded. So "blocking air" for one play during a game doesn't mean that his overall grade will be poor. That said I would be willing to bet that he got a negative grade for the game that you referenced (blocking air). But I cant be sure because I dont have a PFF subscription. The key to PFF is that it is about every single play. It is unlikely that anyone focuses on Zuttah or any other O lineman for an entire game. But in order to evaluate a players performance, that is what you would have to do for the entire game. There are certainty flaws though. Each play is graded on a scale from -2 to 2. The two being the best and the negative two being the worst. I would argue that numbers don't accurately represent the damage that is done to a team when a player commits a penalty because the scale only goes down so far. Zuttah played really well in the Dallas Cowboys game. The only guy on offense that got a higher grade was Marshall. That said JZ committed 3 costly penalties that arent accurately represented in his PFF grade. I would argue that two of the penalties were unfounded, but they were penalties none the less and ended up being drive killers.
