The Theory
Essentially what Beane and the Oakland A’s front office decided to do in the movie was to combine certain stats of their three big free agents. The Kansas City Royals have a very similar situation on their hands heading into 2018. They don’t have enough money to bring back Lorenzo Cain, Hosmer and Mike Moustakas. Instead, they will have to get creative in order to replace their offensive production.
The best way that I can think to do this is to “Moneyball” the heck out of it. The Kansas City Royals are going to need to find some offense for the 2018 season, and they’re going to have to do it on a budget.
In 2017, the combined on-base percentage of Cain, Hosmer and Moose was 1.062. Divide that among the three of them and you get .354. Ideally then, according to the movie, the Kansas City Royals would look to find three players whose average OBP is .354.
To be fair, this is going to be really tough. With the value that is currently placed on guys who can get on base, it’s difficult to find them for cheap. Luckily for KC and Moore, they might be able to fill one of the three positions with someone who’s already in their system.
