While I can see that point, when we're talking about the majors, each pitcher is going to have that happen what, 4-5 times a year max? The worst SS make around 35 errors right? Each starter will be in for what, 1/6 or 1/7 of the total innings pitcher? That's gonna mean they get at most 6 of the SS's errors on the season, and while I have no idea what % of SS errors are balls that are booted vs. throwing errors, lets say all 6 are booted. A good SS will probably only make 10-15 errors at best, right? Simplying it down because it's nearly 4 a.m., that SS might only make 2 or 3 errors for that pitcher during a season. You're basically saying that 4 more errors over the course of 30+ games is that big of a deal to the pitcher's psyche? I just don't see it. Obviously a good SS is better than a bad one, but I have a hard time believing that a pitcher at the major league level can be effected that much by having a fielder behind him make 2-4 more errors than a good fielder at that position would have. (Yes, I know errors are a terrible way to evaluate fielders. But I feel my point still stands, the amount of non-errors of good vs. bad SS still will be very small coming for just one pitcher. Interesting point. I think it may depend on the pitchers style (groundball/flyball) and their mentality. I don't think you can look at the stats in a flat line like that and say each pitcher gets X. You're right that errors are not the best way to judge and when easy groundballs get through time and time again it wears on them.
