League history from before Sleeper

If your league moved to Sleeper from somewhere else (NFL Fantasy, etc.), Sleeper has no record of your seasons before the move. Add that history yourself from your league's dashboard page — one season at a time, or all at once with a CSV.

Bulk import: a CSV with a header row, one row per season. Only the season column is required.

champion, runnerUp, keepers, and notes can hold anything — keepers is free text, so write it however makes sense to you (e.g. "Mike: Mahomes, Kelce | Sarah: Jefferson"). Re-importing a season already on file overwrites every field for that row, so include everything you want kept, not just what changed.

Made a mistake? Click Edit on any season to load it back into the form — fix what's wrong and save. There's also a Remove button per season, and a "Clear all history" option if you want to start over completely.

This is entirely separate, hand-entered data — it never merges with or checks against your live Sleeper stats. If a season you're adding overlaps with real Sleeper-era data, that's on you to reconcile; Homefield doesn't cross-check the two.

This shows up as a History section on your live site, in order from most recent season back — it only appears once you've added at least one season.
