(Today's excerpt originally was published in November 2013.)
"The money doesn't matter. It's not about whether the marginal cost of a win on the free-agent market is five million bucks or $7 million or $13 million; it's about that framework no longer being the way to evaluate signings. The extra dollars a team might spend to bring a player into the fold -- and turn a contract from a sabermetric win to a sabermetric loss -- are meaningless in the big picture because there's just no other good application of those dollars. The opportunity cost of not signing the player isn't 'having the money to sign someone else,' it's 'having cash and no good way to use it.'"
