Not only is Billy Beane‘s Athletics team of the early aughts a true “David Vs. Goliath” story but it‘s also an interesting case study on how so many people could be doing something so wrong for so long due to things like “tradition”. The idea that sabermetrics could help baseball teams succeed was around since the 1970‘s and it took 30+ years for it to be implemented and now it‘s the standard for most teams. Good book, great lesson.
