The Mathematics of a Fair Fantasy Sports Trade
Introduction
We are now rapidly approaching the major league trade deadline of July 31. In our own fantasy baseball leagues, we often try to mimic real-life – and trading is no different. We set up an arbitrary date in the 2nd half of the baseball season, in which we agree to cease trading with our league mates for the remainder of the season.
Some leagues set their internal deadline a few days following the major league one. Some leagues set the deadline to be the All-Star game. Whatever your league’s trade stopping point may be, the idea is to prevent last minute unfairness or possible collusion. As a natural byproduct, having that set date often sparks some league excitement in the waning trading hours!
The title of this article is, The Mathematics of a Fair Fantasy Trade. Often, leagues will allow its individual team members (or commissioner) to vote upon and potentially veto a trade which they deem as “unfair.” These leagues will often state in their constitutions ideas resembling:
All trades should be “fair.” A trade does not necessarily need to be “good” for both sides.
The above verbiage is taken verbatim from the constitution of one of my home leagues. For a number of my other leagues, their bylaws also state something similar. League guidelines often emphasize the notion that fair trades aren’t necessarily good for both sides. They claim that a fair fantasy baseball trade does not necessarily have to be a good one.
I completely disagree with that premise. The truth is that they are one and the same. Any trade that is good for both sides is a fair one. Any trade that is fair, has the realistic potential to benefit both teams.
