About
Who builds Berzerker, and what league-aware actually means.
Berzerker Fantasy Football is a league-aware fantasy football workspace. It is produced by Jole (John Olson) for ESPN and Sleeper leagues that need rankings, draft help, and weekly decisions shaped by their scoring and roster rules instead of a generic board.
What “league-aware” means
A player’s value changes when your league is superflex, pays a tight-end premium, uses unusual flex slots, or sits on a deep bench. Berzerker compares options against replacement value in the league you selected — the scoring, roster construction, and available players in that workspace — not a one-size-fits-all ranking list.
Playoff odds and similar league-report figures are directional estimates from record, scoring, and roster strength. They are not provider projections and they are not a promise about who wins the league.
Data sources
- ESPN and Sleeper: you connect a league so the workspace can import settings, rosters, and standings the provider makes available.
- FantasyPros: consensus rankings are imported through a server-side connection and then matched to the scoring and roster rules of the active league.
- Market research (Edge / props): cached sportsbook consensus lines can power an evaluator that runs your assumptions. That surface is research math, not a sportsbook, not a bet slip, and not gambling advice.
How access works
Invited workspace accounts sign in with a username and password. Paid members can continue with the email on their season pass. A season pass is $29.99 for the NFL Regular Season (this season only). Connecting a league and using the draft and weekly tools happens after you are signed in — there is no guest workspace.
There is no self-serve password reset. If you forget a workspace password, ask your workspace administrator. Paid members without a username should use email access.
What this is not
Rankings, start/sit comparisons, trade values, and Ask Berzerker answers are research aids. They can be wrong. Edge expected-value figures are calculations from the numbers you enter, not a Berzerker recommendation to place a wager. Nothing on this site is legal, financial, or gambling advice.
