Underdog Best Ball Mania IV Strategy: Roster Construction

Using 4for4’s Roster Construction Tool, we recently explored how many players you should draft at each position in Best Ball Mania IV. That laid the groundwork for how fantasy managers should be approaching Underdog drafts, but the Roster Construction Tool is even more powerful and can offer guidance on how those allocations best fit together across all positions.

For the purposes of this research, the primary metric used to measure success will be playoff advance rate over expectation.

In the coming weeks and months, the 4for4 staff will provide more detailed analysis of how to cultivate draft strategy for this tournament.
