I think the idea that greater range leads to more charged errors is a myth, particularly for infielders. It's gotten pretty hard to be charged with an error these days. Nobody is getting charged with an E at the edge of their range. If anything, it's just the opposite...an infielder takes two steps right or left, boots a rather easy play, and 'hit' flashes on the scoreboard. "Not a routine play" says the official scorer. An infielder who ranges far for a ball and doesn't come up with it, or cant make the throw, won't be charged with an E. On the other hand, if he gets to a ball and makes a wild throw, well, he deserves an error, his throw cost his team a base. Errors are a pretty decent way to make one determination about a player's defense. Not the only way, but a good one. Heck, people freak out because they perceive Hunter to have not gotten to a ball or two that they Think someone else might have. Marcus Semien has booted 17 balls at SS for Oakland this year. Which has damaged his team's defense more?
