Your Best Ball draft will define you for the balance of the year. The cold, hard truth is – after you draft, your team is set in stone. So you’ll either be a savage on draft day… or spend the rest of the year in pain.

That’s why we've developed the most potent 2026 Best Ball RB Rankings. They start with our award-winning baseline player projections. Then we layer on ceiling and floor projections to create a true range of outcomes for every player.

But your real edge comes with the Best Ball Factor that's built into the rankings. We study each RB's weekly volatility and apply a multiplier to players that possess spike-scoring upside. That boosts players in the rankings that are more valuable in the best ball format.

The RB rankings you'll find below are customized to Underdog's scoring rules and lineup requirements. We'll add FFPC-specific rankings later this summer.
