Joey Votto is the embodiment of everything the stat heads have been saying for years — that RBIs are a product of opportunity at least as much as talent and that there are far, far better metrics to measure a player’s output. And Votto is, simultaneously, a source of frustration for anybody who has espoused the old adage that “money lies in RBIs,” because heaven knows he has plenty of the former and — this season, at least — not much of the latter.
