Multi-Entry Best Ball Strategy: How to Build a Portfolio of Rosters
Single-entry best ball is about finding the best single roster. Multi-entry best ball is about building the best collection of rosters. A single-entry manager optimizes for the highest expected single-team score. A multi-entry manager thinks about exposure: how much of my portfolio is on any given player, how correlated are my rosters, and do I have enough differentiated upside to hit across multiple rosters in a single tournament?
Multi-Entry Quick Reference
| Decision | Guideline | Common mistake |
|---|---|---|
| Tier 1 exposure (consensus top-3 at position) | 40–60% of your rosters | Going 80–90% on one elite RB — one Week 1 injury ends your tournament |
| Tier 2 exposure (clear starters, high confidence) | 20–40% | Underexposing to high-value players you have strong conviction on |
| Speculative/upside plays | 5–20% | Same contrarian player on 60% of rosters — now it is not contrarian, it is just concentrated risk |
| Stack differentiation | 3–5 different primary QB-WR stacks across your portfolio | All 20 rosters stacking the same QB and WR1 — one player’s season determines your entire tournament |
| Roster type balance | ~40% chalk-leaning, ~40% moderate, ~20% high-upside contrarian | All chalk (no ceiling to win) or all contrarian (no floor to cash) |
| Draft timing | Spread drafts across August; use early drafts for chalk, late drafts for contrarian deviations | All 20 rosters drafted in week 1 of August before training camp information matures |
Why Multi-Entry Exists
Multi-entry tournaments (like Underdog’s Best Ball Mania) award prizes to the top percentage of finishers — not just first place. In a large tournament with thousands of teams, finishing in the money requires a genuinely elite score. A multi-entry manager’s strategy is to give themselves multiple chances at that elite score.
If any single best ball roster has a 1% chance of finishing in the top prize pool, having 20 well-constructed rosters gives you a much better collective chance than having 1 — provided those 20 rosters are not all the same (which would just be spending 20x to get the same 1 outcome).
Exposure Management
Exposure is the percentage of your rosters that include a specific player. If you have 20 rosters and 10 include Player A, you have 50% exposure to Player A.
High exposure magnifies results across your portfolio. If Player A has a great year, your portfolio wins big. If he busts, your portfolio suffers. Managing exposure prevents any single player from determining your entire tournament outcome.
Why Your Rosters Cannot All Be the Same
QB differentiation: Drafting different QBs across your rosters means one QB having a great year lifts only some of your rosters — and another QB’s big year lifts different ones.
RB differentiation: RBs are injury-prone and high-variance. Having different RB1s across rosters creates a portfolio where different injury scenarios benefit different teams. Spreading RB exposure handles this variance.
Stack differentiation: Each roster should ideally feature a different primary QB-WR stack. Spread your stack exposure across 3–5 different QBs.
Chalk vs. Contrarian Rosters
Chalk rosters: built heavily around consensus top-ranked players. In a large field, chalk rosters often finish around average — most of the field also drafts those same players. Chalk gives you a floor, not a ceiling.
Contrarian rosters: deviate from consensus by taking players with low ownership but legitimate upside. If that player hits, your contrarian roster finishes far above average. If he busts, the roster underperforms — but that is acceptable when you have multiple rosters.
The right balance (multi-entry portfolio):
- A few chalk-heavy rosters for foundational exposure to consensus best players
- Several rosters with moderate chalk mixed with specific upside plays
- A few fully contrarian rosters with unique stacks and low-ownership players designed for high ceiling and high variance
Practical Portfolio Management
Spread your drafts across August. New information arrives constantly during training camp: depth chart changes, injuries, role confirmations. Early drafts → chalk rosters. Late-August drafts (when training camp information is most complete) → your biggest deviations from consensus.
Track your exposure while drafting. Keep a spreadsheet or use a platform’s portfolio tracker to monitor current exposures. If you accidentally drafted 70% on one player across 10 rosters, consciously avoid that player in your remaining drafts.
Small multi-entry (5–10 rosters): Focus on exposure management across a smaller set. Cap your top exposure at 50–60% max and ensure each roster has a distinct primary stack.
Large multi-entry (20–100+ rosters): Portfolio management becomes the primary skill. Consciously build chalk, moderate, and contrarian rosters in an approximate ratio.
