Real-time value-based recommendations, multi-platform ADP arbitrage, and live opponent scouting — rendered seamlessly in your native Chrome side panel.
Stop relying on static cheat sheets. Mega Brain Fantasy recalculates the state of the entire board after every single pick.
Calculates real-time Value Over Replacement Player (VORP) customized to your league's roster settings, scoring format, and positional drop-offs.
Cross-references Sleeper ADP against ESPN, FantasyCalc, and FFC to find massive market inefficiencies and draft steals before your opponents.
Detects when teams start panic-drafting positions (e.g. 4 straight QBs) and alerts you to pull the trigger before the tier falls off a cliff.
Visual scarcity meters show exactly how depleted each position is, helping you know whether you can wait on a QB or need to strike now.
Tracks every team's roster construction, identifies their weaknesses, and predicts who will snipe your targets before your next turn.
Once the draft concludes, receive an instant 1–12 power ranking of all teams with statistical Z-scores and positional letter grades.
Whether your league drafts Standard, Half-PPR, Full PPR, Superflex 2QB, or TE Premium, Mega Brain Fantasy automatically detects your Sleeper league settings and dynamically recalibrates its VORP models in real time.
Instant Sleeper API Integration
Connects to your Sleeper draft room and automatically parses roster slots, reception values, passing TD multipliers, and bench depth without any manual configuration.
Modern Industry Standard
Equally weights rushing volume and target shares. Calibrated to match Sleeper and ESPN default redraft league rules with balanced positional baselines.
High Reception Volume
Maximizes the value of pass-catching workhorses (Achane, Gibbs, McCaffrey) and elite slot targets with high target share and weekly reception floors.
Touchdowns & Pure Rushing
Elevates touchdown machines and pure bellcow rushers (Derrick Henry, Jonathan Taylor, Saquon Barkley) while devaluing satellite backs and low-touchdown receivers.
Quarterback Premium
Doubles the starter QB demand from 12 to 24+ signal-callers, vaulting elite QBs (Josh Allen, Lamar Jackson, Jayden Daniels) into high Round 1/2 VORP recommendations.
Positional Advantage
Awards extra points on tight end receptions, boosting elite difference-makers (Brock Bowers, Trey McBride, George Kittle) up 1–2 full draft rounds.
Sleeper draft rankings vary between the other major drafting platforms. Mega Brain Fantasy surfaces underpriced players, and players that are overvalued on other platforms, for massive draft value.
