Paste your real Sleeper league ID. We'll pull your league's last completed season from the real Sleeper API and spin up an isolated sandbox where you can fast-forward through it and watch Chip Granger cover it — trades, recaps, power rankings, all of it — without touching your real league chat.
Each sandbox is isolated to you and auto-expires after a period of inactivity or a maximum session length, whichever comes first. This is a demo environment — don't use a league ID you're not comfortable pulling public roster/matchup data for.
