The Math of a Perfect Season

The game is named for the rarest result in it. Going 17-0 should feel like threading a needle — reachable often enough to chase, rare enough to mean something when you get there. Hitting that balance took a specific design choice.

Why the board deals twelve pairs, not nine

You fill nine positions, so the obvious design would be to deal exactly nine team-and-era pairs and let you draft one player from each. We tried it. The problem: with nine forced pairs and no choices, you're at the mercy of whatever you're handed. Optimal play averaged something like a 13-4 to 14-3 season, and a perfect 17-0 was possible only about one day in three weeks — far too rare for a game that lives or dies on the promise of a perfect season.

So the daily board deals twelve pairs and lets you pass on three of them. Those three passes are what turn the board from a slot machine into a game of decisions: you can steer around a bad matchup, wait out a thin position, and shape a roster instead of accepting one. With that agency, a true 17-0 becomes reachable roughly four days in every three weeks — rare, but a real target you can play toward.

Wins don't rise in a straight line

Once your roster is graded into a single strength number, the simulator maps that onto a 17-game record along a curve, not a ruler. At the low end, adding strength buys you wins slowly. Near the top, each additional point of strength is worth more — until the final stretch from "great" to "perfect," which is the steepest climb of all.

That's deliberate. It means a very good roster reliably posts a very good record, but a flawless one is required to run the full table. You can't buy the last win or two with a single superstar; you need genuine strength and balance across all five phases and the era-diversity bonus all working together. Miss on any one and the curve leaves you a game or two short.

What record should you expect?

A rough guide to where rosters land:

• 10-7 ↓A roster with a soft spot or two. Fun, but the weak link is dragging you down — revisit rule one.
• 12-5A solid, balanced team with no stars. Respectable, and the baseline good play should clear.
• 14-3 to 15-2A strong, balanced roster spread across eras. This is what a well-drafted board looks like most days.
• 16-1One phase came up a hair short of perfect. Agonizingly close — usually a single pick away.
• 17-0Everything aligned: top-tier talent, no weak link, a diverse timeline, on a board that allowed it. The whole point.

Because the daily board is the same for everyone, some days a 17-0 is genuinely on the table and some days the best-possible roster tops out at 16-1. That's part of the fun of a shared board: when someone posts a perfect season, everyone knows it was the same twelve pairs — and can try to match it.
