I think, Moneyball's legacy is bifurcated. On the one hand it opened eyes that there was some value in applying a kind of economic analysis to the consideration of ballpayers, or sports overall and what made the book so effective and important, was that it captured a moment when that kind of thinking met with entrenched resistance, and Beane's own cognitive dissonance about his own career, and a kind of uneasy hybrid future was born. One the other hand, its notoriety made it way too easy for people who never fully appreciated all of the above, to think of "Moneyball" as a monolithic thing that meant nerds with slide-rulers were running baseball. Such a great book, (and a fun but flawed movie) and so complicated!
