Imagine that you are playing video game baseball.
Your team is projected to win 84 games, but the last wild card position is projected to require 88 wins. You have $15 million left to spend, and no more. And – because this is a video game – every free agent will sign with your team, if you meet their price.
What would you do?
In a videogame world, the answer is almost simple. You would take each of the remaining free agents, estimate how many additional wins they would earn for you and divide that into their price.
