Your league fingerprint

Three chapters. One honest picture.

League History organizes years of activity into the questions dynasty managers actually argue about: who wins, who deals, and who builds the strongest franchises.

01

Competition

Compare all-time standings, scoring records, and all-play performance that strips away schedule luck.

02

Trade Culture

Find favorite partners, blockbuster seasons, deadline behavior, pick journeys, and manager-to-manager trade volume.

03

Team Building

Measure draft DNA and roster roots to see which teams are homegrown and which were assembled through deals.

Beyond the schedule

See who was good—and who was just lucky.

Standings only record the opponent you happened to face. The all-play table compares each weekly score against the entire league, revealing the teams that consistently performed even when the schedule did not cooperate.

  • Compare official records with schedule-neutral all-play results
  • Find the strongest and unluckiest seasons in league history
  • Track all-time scoring leaders and single-season records
  • Keep every result tied to the season and franchise behind it

League History questions

What the all-time view includes.

How is this different from a Yearbook?

A Yearbook preserves one season’s story. League History combines every season to reveal all-time records, rivalries, and long-term behavior.

What does all-play mean?

Each weekly score is compared with every other team that week, making team strength easier to separate from fortunate matchups.

Does it follow renamed teams?

Yes. Franchise history stays connected through team-name and manager changes so older records remain readable.
