Daily Fantasy Sports (DFS): The Complete Guide

Daily Fantasy Sports lets you build lineups and compete for cash prizes. Here's how to get started.

DFS Basics

What is DFS?

Build a roster of real players within a salary cap, earn points based on their real-game performance, compete against other users for prizes.

DraftKings vs FanDuel

DraftKings: More contest variety, higher prize pools FanDuel: Simpler scoring, better for beginners

NFL DFS Strategy

Roster Construction (DraftKings)

• 1 QB
• 2 RB
• 3 WR
• 1 TE
• 1 FLEX (RB/WR/TE)
• 1 DST (Defense/Special Teams)

Salary Cap Strategy

Stars and Scrubs:

• Pay up for 2-3 superstars
• Fill rest with cheap value plays

Balanced:

• Spread salary evenly
• No huge stars, no min-salary punts

Stacking:

• Pair QB with his WR/TE
• Increases upside in tournaments

Key Stats to Target

High-ceiling players:

• WRs in shootouts
• RBs with goal-line touches
• QBs vs weak secondaries

Consistent floor:

• Pass-catching RBs (PPR)
• Slot WRs (high targets)
• Elite TEs

Ownership Leverage

In tournaments, you need low-owned players who perform well.

Chalk plays: High-owned (25%+)

• Avoid in large tournaments
• Safe for cash games

Contrarian plays: Low-owned (<10%)

• Needed to win big tournaments
• Higher risk

Cash Game vs Tournament Strategy

Cash Games (50/50, Double-Ups)

Goal: Finish top 50% to profit

Strategy:

• High floor, consistent players
• Avoid risky low-owned plays
• Pay up for elite RBs and QBs
• Minimize risk

Typical lineup:

• Expensive RBs/WRs with safe workload
• Avoid boom-or-bust players

Tournaments (GPPs)

Goal: Finish top 10-20% for big prizes

Strategy:

• High ceiling, low ownership
• Stacking (QB + WR combos)
• Contrarian plays
• Accept higher bust rate

Typical lineup:

• Cheap breakout candidates
• Game stacks (QB + 2-3 pass catchers from same game)
• Leverage low-owned chalk fades

Lineup Building Process

Step 1: Identify Core Plays

Pick 2-3 players you're confident in (regardless of ownership).

Step 2: Find Value

Identify cheap players ($4,000-5,000 on DK) who will play significant snaps.

Sources:

• Injury fill-ins
• Favorable matchups
• Increased workload players

Step 3: Stack Correlations

QB + WR stack: If QB does well, WR likely does too Game stack: Multiple players from high-scoring game Bring-back: Pair opposing team's WR with your QB stack

Step 4: Optimize Remaining Spots

Use leftover salary to maximize projected points.

Advanced DFS Concepts

Game Theory

In tournaments, winning requires differentiation.

Leverage:

• Fading chalk when ownership is too high
• Playing low-owned players in good spots
• Zigging when others zag

Ownership Projection

Estimate how popular players will be:

• Vegas totals (high = popular)
• Price (expensive = popular)
• Narratives (hyped players = popular)

Goal: Find underowned players in good spots

Late Swap

FanDuel allows lineup changes before each game starts.

Strategy:

• Wait for inactives list
• Pivot if your player sits
• Adjust to breaking news

Common DFS Mistakes

❌ Paying down at QB (QB is most important position) ❌ Playing every contest (focus on your edges) ❌ Ignoring ownership (in tournaments) ❌ Not diversifying lineups (enter multiple different lineups) ❌ Chasing losses (increasing stakes after bad week)

✅ Study Vegas lines and totals ✅ Check injury reports before lock ✅ Use multiple lineups in tournaments ✅ Track your ROI by contest type ✅ Bankroll management (never >10% in one week)

DFS Bankroll Management

Weekly Allocation

• Max 10% of total bankroll per week
• 5% in cash games (safer)
• 5% in tournaments (higher variance)

Contest Selection

Beginners:

• 70% cash games
• 30% small-field tournaments

Experienced:

• 40% cash games
• 60% tournaments (diversified across many)

Tracking ROI

Calculate weekly:

• Total entry fees
• Total winnings
• ROI% = (Winnings - Fees) / Fees × 100

Break-even: ~0% ROI Good: 10-20% ROI Great: 25%+ ROI

Is DFS Profitable?

Reality check: Most DFS players lose money.

To profit:

• Study extensively (10+ hours/week)
• Specialize in one sport
• Bankroll management
• Accept losing weeks
• Long-term edge (52-55% ROI rare)

Treat DFS as entertainment with a chance to profit, not a guaranteed income source.
