I wonder what the motive for the players is for this. I know many times they try to avoid too much of the statistical side not because they don't like it, but because they don't want any focus on that to affect them on the field. At the same time though, it can be hard to evaluate exactly what your weaknesses are on defense (as far as I know, position players don't look at videos of their defense nearly as much as their batting or opposing pitchers) and so their section could give them a fair objective opinion. Then again, who knows. They often have very different perspectives about things than fans. It looked to me like they were genuinely curious. They also seemed to think the book was fair to them. You're right, players have a different take on things than fans. That's probably why Theriot made his comment about errors. Pitchers, such as Maddux, talked about wins. That's their perspective. After reading what they said about Theriot I can see why the players would like it. He goes out of his way to not say anything really bad about Theriot. On the other hand he has poor range to the hole and his weak arm keeps him from making plays there. I suppose that would be true of a lot of SS. but it still seems like he's sugarcoating Theriot's defensive flaws.
