Track exposures, CLV, stacks, combos, and construction across both DraftKings and Underdog.
Managing a high-volume best ball portfolio requires aggregating data from Underdog and DraftKings simultaneously. Our Portfolio Tracker lets you upload draft screenshots or CSV exports to instantly display real-time player exposure percentages across every roster, preventing dangerous over-exposure to high-variance assets.
CLV (Closing Line Value) measures whether you drafted a player earlier or later than their final ADP position. Positive CLV means you got a player before the market caught up — a sign of sharp drafting. Our tracker calculates CLV for every pick against Underdog and DraftKings ADP tables automatically.
The tracker processes every roster in your portfolio and surfaces exposure percentages by player, position, and NFL team. It also identifies stacks (QB+pass-catcher combinations), combos (player pairs appearing across multiple rosters), bye week risk concentration, and playoff schedule strength.
| Metric | What It Tracks | Why It Matters |
|---|---|---|
| Player Exposure % | % of rosters containing each player | Prevents over-concentration in volatile assets |
| CLV Score | Draft position vs. closing ADP | Measures draft sharpness per pick |
| Stack Combos | QB + WR/TE combinations across rosters | Identifies correlated upside clusters |
| Bye Week Risk | Roster exposure during NFL bye weeks | Flags rosters with stacked byes |
| Playoff Schedule | Matchup quality in weeks 15–17 | Surfaces rosters built for title-round upside |
