Return of the Stack: How to Use the Win Rate Explorer and Roster Construction Explorer Together to Build a Superflex Juggernaut, Part 6

In Part 6 of this series, Kevin Szafraniec evaluates the team stack data in RotoViz’s Best Ball Win Rate Explorer to pinpoint the combinations that have historically provided the most profitable returns in Superflex best ball leagues.

So far in this series, we have covered a lot of information:

The final installments of the series will focus on stacking and the practical application of the principles we have covered in two FFPC Superflex Best Ball Tournament drafts.

Anyone who plays best ball knows there are certain players “you have to have” every season to come out at the top of the leaderboard in large-scale tournaments. When we stack these players alongside other members of their offenses, it exponentially increases the odds of advancing through our pods during the fantasy playoffs and finding ourselves with a big payout at the end of the season.

However, there is a case to be made that not all stacks are created equal. For fantasy managers who go about building their rosters the wrong way, stockpiling assets on the same offense can actually do more harm than good.

In this exercise, we will jump into the Best Ball Win Rate Explorer (WRE) and look at how stacks have impacted the success of teams in FFPC Slim Superflex best ball leagues over the past six years. It is important to note that when we are talking about positional rankings in this article (i.e., WR1, WR2, WR3, etc.), we are making these distinctions using ADP, not end-of-season scoring.

For those who may be unfamiliar with the FFPC Superflex Best Ball Tournament, each draft consists of 20 rounds, and starting rosters feature one quarterback, two running backs, two wide receivers, one tight end, one traditional flex spot, and one superflex spot. Scoring settings are TE-premium, meaning TEs are awarded 1.5 points per reception while every other position operates under normal PPR scoring.

Breaking Down the Passing Game

It makes sense to start this exercise by looking at the edges we can gain by matching QBs with the other positions on their offense.
