1) Foundations & Formats
Build the core vocabulary and understand how we use hypothetical “contest” formats purely as teaching devices. We do not host real-money play — this is education only.
Key Terms
- Slate — a set of games used in a lesson scenario; lets us compare choices on the same day.
- Roster — a hypothetical lineup we build for learning (no entries, no submissions).
- Ceiling / Floor — illustrative high/low outcomes for a player in a scenario.
- Variance — how spread out outcomes are vs. a projection.
- Correlation — when player outcomes tend to move together (positive/negative).
- Ownership (conceptual) — class discussion proxy for “popularity,” not real data.
Why “Formats” in Class?
We use familiar fantasy contest ideas to explain trade-offs (stability vs. upside) and to structure exercises. They are analogies, not invitations to play.
- Compare choices under different risk preferences.
- Practice normalizing and pacing statistics.
- Discuss roster roles and correlations using safe, static examples.
Do / Don’t
- ✅ Do treat all examples as classroom exercises.
- ✅ Do ask “what changes my evaluation?” (pace, roles, weights).
- ❌ Don’t seek real-money links; we don’t provide any.
- ❌ Don’t read examples as advice to enter paid contests.
Head-to-Head (H2H) — Stability Lens
We discuss stability: prefer players with tighter floors and less variance for the lesson’s objective.
- • Emphasize consistent roles (openers/key starters, high-minutes players).
- • Limit volatile, all-or-nothing profiles.
- • Example focus: “reduce avoidable downside.”
50/50-Style — Balance Lens
Teach balance: combine dependable cores with limited, reasoned upside swings.
- • Stabilize with roles; add 1–2 controlled variance pieces.
- • Practice normalization to compare similar candidates.
- • Example focus: “don’t overreact to one hot performance.”
GPP-Style — Upside & Correlation Lens
Explore variance & correlation: how stacking roles influences ceiling scenarios in class discussions.
- • Identify correlated roles (e.g., top-order + supporting roles, passer + receiver).
- • Accept more variance for educational what-ifs.
- • Example focus: “when correlation helps or hurts.”
Role Archetypes (Illustrative)
Use these archetypes to describe how a hypothetical player contributes in different teaching scenarios.
Archetype | Strength | Risk | Best Lens |
---|---|---|---|
Anchor | Stable minutes/usage; steady baseline | Lower ceiling | H2H / 50-50 |
Value | Efficient points per unit “cost” (teaching proxy) | Role can change suddenly | 50-50 |
Ceiling Swing | High upside in certain matchups | Volatile floor | GPP-style |
Correlation Piece | Benefits when paired with specific roles | Dependent on others’ performance | GPP-style |
Mini Exercise: Choose a Core
You have 3 hypothetical players. Which two form a more stable “core” for an H2H lens?
- Player A: steady role, modest ceiling, almost no penalties
- Player B: occasional spikes, medium role security
- Player C: huge ceiling, frequent penalties
Show discussion points
• For H2H, A + B often forms a steadier baseline than A + C.
• If you switch to a GPP-style lens, B + C might be discussed for upside correlation.
Teaching Notes
- • Normalize stats before making close comparisons.
- • Consider pace/tempo adjustments if a scenario implies it.
- • Roles can be sticky or fluid — state your assumptions clearly.
- • Correlation helps explain why certain pairs rise/fall together.
Quick Self-Check
- Define “variance” in your own words and give a sports example.
- Why might an “anchor” be preferred in an H2H lens?
- Give one example where correlation could be positive and one where it might be negative.

2) Scoring Theory (Classroom)
Use a sport-agnostic scoring template to illustrate how points accrue. Adjust weights to explore different teaching scenarios. This is not a betting model — it’s a learning tool.
Event | Example Weight | Why This Matters |
---|---|---|
Primary Stat (run/goal/point) | +1.0 | Baseline contribution to illustrate consistency. |
Bonus (milestone achieved) | +3.0 | Reinforces peaks in performance; shows upside. |
Penalty (turnover/wicket) | −1.0 | Teaches trade-offs; why minimizing mistakes matters. |
Efficiency Bonus (per-rate) | +0.5 per unit above avg | Lets students see normalization in action. |
Adjusting Weights
Try tweaking these weights in a spreadsheet. Watch how the ranking of hypothetical players changes. Ask:
- • Does a heavier penalty reward stability or upside?
- • How does increasing the bonus change variance?
- • Which roles benefit under each setup?
Mini Exercise: Compare Two Players
Player A has 10 primary stats, 1 bonus, 2 penalties. Player B has 8 primary stats, 2 bonuses, 0 penalties. Using the template above, who scores higher?
Show worked answer
• A = (10×1.0) + (1×3.0) − (2×1.0) = 11
• B = (8×1.0) + (2×3.0) − (0×1.0) = 14
B wins under this setup. Try changing the penalty weight to −2.0 and recalc — see how it flips!
Teaching Notes
- • This template is intentionally simple — expand as lessons get deeper.
- • Highlight the difference between projection (expected score) and variance (spread).
- • Show how normalization (per-minute, per-over) affects comparisons.
- • Encourage students to document their assumptions before calculating.
Quick Self-Check
- What happens to player rankings if you double the penalty weight?
- Why might a bonus for efficiency change your preferred roster?
- How would you normalize these scores across different slates?

3) Normalization & Pace
Compare apples to apples: put stats on consistent scales and adjust for tempo so evaluations are fair. This module shows how to normalize data and account for pace effects — two keys to making teaching scenarios realistic.
Normalization Basics
Normalize data to a common baseline before comparing players:
- • Per-minute / per-over rates (remove playing-time bias).
- • Z-scores (how many standard deviations above/below mean).
- • Min-max scaling (rescale to 0–100 for visual teaching).
- • Outlier handling (cap extremes to reduce noise).
Pace Adjustments
Accounting for tempo (overs, possessions, balls faced) is crucial for fairness:
- • League/team tempo affects counting stats.
- • Regression to mean for extreme paces.
- • Scenario testing across different tempos.
- • Use pace-adjusted stats to teach “environment effects.”
Illustrative Normalization Table
Player | Raw Points | Minutes | Per-Minute | Z-score |
---|---|---|---|---|
A | 24 | 30 | 0.80 | +0.4 |
B | 20 | 18 | 1.11 | +1.2 |
C | 30 | 40 | 0.75 | −0.1 |
B looks strongest on a per-minute basis despite lower raw points.
Mini Exercise: Pace Context
Two hypothetical players: Player X has 15 points in a fast-paced environment (100 events), Player Y has 12 points in a slow environment (60 events). After pace adjustment, who is more efficient?
Show discussion
Teaching Notes
- • Always state whether stats are raw or pace-adjusted.
- • Show how environment can create illusions of performance.
- • Encourage students to try different normalization methods.
- • Link to your Scoring Theory module to see how weights interact with normalized data.
Quick Self-Check
- Explain why per-minute rates are fairer than raw totals.
- Give one scenario where pace adjustment flips your ranking of two players.
- What’s the difference between z-scores and min-max scaling?
Education-only. We do not host contests or process payments. Adults 18+ only. Not available in Assam, Andhra Pradesh, Odisha, Telangana, Nagaland, Sikkim, and Meghalaya.
4) Roster-Building Theory
Learn to structure a hypothetical lineup by thinking in roles and correlations instead of chasing random spikes. This module is for classroom exercises only — no entries or prizes.
Think in Roles
Assign each player a role archetype rather than just a projection:
- • Anchor: steady minutes and usage, low variance.
- • Value: efficient at a lower teaching “cost.”
- • Ceiling Swing: high upside, volatile floor.
- • Correlation Piece: benefits when paired with certain roles.
Combining these archetypes teaches balance, upside, and risk management in a controlled classroom setting.
Understand Correlations
Discuss how players’ outcomes can be linked and how that affects your hypothetical lineup:
- • Positive correlation: when one succeeds, the other often benefits.
- • Negative correlation: when one gains, the other loses opportunities.
- • Uncorrelated: independent outcomes, used for diversification.
Use “stacking” or “anti-correlation” as teaching experiments, not real-money tactics.
Illustrative Hypothetical Lineup
Slot | Player (hypothetical) | Role | Correlation |
---|---|---|---|
1 | Opener A | Anchor | Paired with Supporter B |
2 | Supporter B | Correlation Piece | Positive with Opener A |
3 | Wildcard C | Ceiling Swing | Independent |
Discuss how this mix of roles affects stability and upside.
Mini Exercise: Build a Balanced Core
Choose 3 hypothetical players from the list below to form a balanced core for a class scenario:
- A: Anchor with low variance
- B: Ceiling Swing with huge upside but penalties
- C: Value player with moderate role security
- D: Correlation piece with Anchor A
Show discussion
Teaching Notes
- • Start with roles first, then add numbers (projection/variance).
- • Show how correlation can amplify both risk and reward.
- • Encourage students to state their assumptions before building lineups.
- • Remind them that this is a classroom exercise, not strategy advice.
Quick Self-Check
- List three role archetypes and what they represent.
- Explain how positive correlation can help in a hypothetical lineup.
- Why might you include an “independent” player in a roster?

5) Optimization (Education-only)
Transform your teaching scenario into a transparent spreadsheet model. This module introduces objective functions, constraints, and how to test heuristics safely. No scripts, no bots, no automation for real-money play — purely learning tools.
Define an Objective Function
Decide what you’re maximizing or minimizing in your class exercise:
- • Total projected points (sum of normalized scores).
- • Ceiling potential under a given scenario.
- • Stability index (variance minimization).
Write it as a simple formula in a spreadsheet so students can see it update live.
Apply Constraints
Add realistic limits to mimic roster rules — but keep it educational:
- • Position limits (e.g., max 2 anchors, 1 ceiling swing).
- • Teaching “budget” cap (a proxy for resource allocation).
- • Minimum/maximum number of correlated players.
Show how changing a constraint shifts the optimal lineup.
Illustrative Optimization Table
Player | Projected Points | Role | Teaching Cost | Selected? |
---|---|---|---|---|
Anchor A | 25 | Anchor | 8 | ✅ |
Ceiling Swing B | 30 | Ceiling Swing | 12 | ✅ |
Value C | 18 | Value | 5 | ✅ |
Students can change “Teaching Cost” or add constraints to see which lineup optimizes under a given rule set.
Mini Exercise: Shift the Constraint
Using the table above, what happens if you lower the “budget cap” from 25 to 20? Which player drops out?
Show discussion
Teaching Notes
- • Always display your objective and constraints transparently.
- • Let students experiment with changing one variable at a time.
- • Emphasize that this is a math exercise, not a lineup tool for real play.
Quick Self-Check
- Write a simple objective function for a hypothetical roster.
- List three constraints you might add to make it realistic.
- Explain how changing one constraint affects the “optimal” lineup.
