What stat better tells how a pitcher performs than ERA? Errors behind the pitcher are removed so it’s directly related to who he’s letting on base and what happens afterwards.???
PFF is most certainly not super accurate. It's like looking at ERA in baseball to try and judge a pitcher solely off that. ERA is useful, especially when it's combined with other stats. But it's impossible to make an accurate opinion on how good a pitcher is based on ERA alone.
PFF is even worse because the stat itself is not grounded in actual hard data. Instead, it's opinion based.
I can tell you I watched every Vols game. Some even multiple times. I also watched other SEC teams all season. I can assure you Lance Heard was not one of the worst OL on this team, much less the conference.

I’ll give you the park thing. That’s legit but I still thing ERA is best even though it isn’t perfect. WAR I’m not sure about as I don’t know what all goes into that formula. Defense is accounted for in ERA. Errors go as unearned runs, not earned. SO rates are a single factor contributing to ERA so not sure how that’s more important than ERA.WAR for one. Then there's FIP (which is calculated into Fangraphs WAR). But the best maybe xwOBA.
ERA doesn't account for park factors. A pitcher with a 3.50 ERA in Colorado (the most hitter friendly park in the MLB) is a vastly more impressive than a pitcher with a 3.50 ERA in San Diego (perhaps the most pitcher friendly park in the MLB). ERA also doesn't account for defense. A pitcher with a poor defense will often have a worse ERA than a pitcher with a good defense, through no fault of his own. And obviously, pitchers that strike out hitters at a high rate are more valuable because they remove the defense from the equation all together. Advanced stats take these things into account.
Errors are only a portion of the problem.I’ll give you the park thing. That’s legit but I still thing ERA is best even though it isn’t perfect.

Eh, not really. PFF can be useful, but I would not call it super accurate.
They have no way of knowing what a player's assignment was on any given play. If a CB gives up a long TD because he was supposed to have safety help over the top, but the safety doesn't rotate over, then PFF will incorrectly penalize the CB. And there are a probably a dozen or so plays like that over the course of every game where they penalize someone for something that wasn't their fault.
They’re pretty good at grading linemen. You don’t have to know the assignment to grade if an offensive lineman held his own on a given play.
Some things are harder to grade for sure, like secondary play and WR play. But PFF openly acknowledges that
Interesting on that last part. I’ll check it out.Errors are only a portion of the problem.
1. Just because a player doesn't get charged with a error, doesn't mean he had no affect on the play. Consider someone like Andrelton Simmons. He had amazing range and an amazing arm. Think about how many more hits he took away than the average SS because his elite range allowed to get him to more balls.
Now consider someone like Vaughn Grissom who we watched last year, and we know was a poor defensive SS. He couldn't get to half the balls hit that Simmons and his arm was well below average. He would have allowed a ton more hits than Simmons did that would not get accounted for as errors.
If you had a very good defensive team, your defense would generate far more outs than the average team, and your pitchers' ERA would benefit. If you had a poor defensive team, your defense would give up far more hits than average, and your pitchers' ERA would suffer.
2. WAR is an all encompassing stat. It isn't perfect, but it attempts find a true value of a pitcher. It considers innings pitched, FIP (fielding independent pitching), park factors, etc. It produces a far more accurate picture of a pitchers actual value.
There still are assignments they can't know about. Say an OT was expecting help from the TE but didn't get it. Or a guard pulling was late or simply didn't pull. Missed assignments happen. PFF can't account for that.
But yes it's still easier to judge than other positions overall because, typically, it is one on one.
