Multi-Season Dynasty Analytics: How We Track Your Sleeper League Across Years
feature · analytics
Dynasty leagues span years. Managers rebuild, rivalries develop, and records pile up across seasons. All of that data should be connected.
Automatic Season Discovery
When you enter your Sleeper username, we don't just pull your current league. We follow Sleeper's previous_league_id chain to trace your league's full history, pulling in every connected season automatically.
Select one season for a focused view, or combine multiple seasons to see the big picture. Every feature in the app respects your selection.
Combined All-Time Records
Multi-season analysis merges your data into a unified view:
- All-time win/loss records
- Cumulative points for and against
- Cross-season head-to-head records across four years and 30+ matchups
- Longest streaks that carry across season boundaries
Performance Trends Over Time
Our weekly scoring charts stitch together data across seasons, creating a continuous timeline of your league. Spot which managers have been consistently strong versus which ones had a single dominant year. Week labels show the season context (e.g., "'24 W1", "'25 W14") so you always know where you are in the timeline.
Score distribution views show how each manager's scoring range, consistency, and average have evolved, showing who has improved their team over time and who has slipped.
Cross-Season Trade Analysis
Dynasty trades involving future draft picks don't resolve for months. Our trade grading follows those picks across seasons. When the pick is used in a future draft, we track which player was selected, what they're worth now, and how many fantasy points they've scored.
Combined trade analysis reveals long-term patterns: which managers consistently win deals over multiple years, who trades most actively, and how trade frequency correlates with league success.
Per-Season Switching
Sometimes you want to zoom in on a single year. Switch between "All Leagues" and any individual season at any time. Every tab (standings, performance charts, trades, drafts, matchups) updates instantly.
