17. “What is an error?
“It is, without exception, the only major statistic
in sports which is a record of what an observer
thinks should have been accomplished.
“But the fact of a baseball error is that no play
has been made but that the scorer thinks it
should have.
“It is, uniquely, a record of opinions.”
-- Bill James, 1977

they lied.
And the lies they told led the people who ran
major league baseball teams to misjudge their
players, and mismanage their games.”
-- Michael Lewis, author of Moneyball
