The key dilemma around Moneyball, the book by Michael Lewis and the movie based on it (I recommend both), is pretty simple.
The New York Yankees had a payroll of $126 million in 2002. The Oakland A’s had a payroll of only $40 million. How does an underfunded, outgunned outfit like the A’s compete with the Yankees? As A’s General Manager Billy Beane puts it in the movie: “There are rich teams, and there are poor teams. Then there’s 50 feet of crap. And then there’s us.” - in Daily Reckoning
