The Z Files: Fallacies of Keeper League Inflation

The Z Files: Fallacies of Keeper League Inflation

This article is part of our The Z Files series.

For the past month, the focus of this column has been on the flaws of valuation theory and how they affect assembling a fantasy roster. Today, we'll wrap up the series with a look at how valuation is misapplied in keeper formats.

Everyone playing in auction keeper leagues is familiar with the concept of inflation. In the aggregate, players are retained for an amount below what they would collectively sell for in a redraft scenario. The repercussion is the remaining players are purchased for inflated prices. If they sold for the market rate in a redraft league, everyone would leave a ton of money on the table.

Conventionally, an inflation factor is calculated, and all the redraft prices are adjusted linearly.

1. Sum up the total salaries of every keeper

2. Sum up the redraft price of every keeper

3. Determine the total dollars everyone has to spend

4. The inflation coefficient is (#3 - #1)/(#3 - #2).

5. Multiply the redraft price of every player available by #4

By means of example:

12 team league with a $260 per team budget. A total of $1600 worth of players are frozen for $1200.

1. $1200

2. $1600

3. $260 x 12 = $3120

4. (3120 – 1200)/(3120 – 1600) = 1.263

5. The redraft bid price of everyone available is multiplied by 1.263.

This means it takes a $57 bid to buy a $45 Ronald Acuna, or $51 to purchase a $40 Gerrit Cole.
