Do I need an ESPN or Sleeper league?
Sign in first, then connect a league you already play. Berzerker imports the settings, rosters, and standings the provider makes available. There is no guest draft room.
How it works
Connect your league. Draft with context. Play the week.
Berzerker Fantasy Football is a league-aware fantasy football workspace for ESPN and Sleeper. You sign in, import the league you already play, and use one board from draft night through the weekly start/sit.
01 Sign in to a workspace
Invited accounts use a username and password. Paid members can continue with the email on their season pass. There is no guest workspace and no self-serve password reset — ask a workspace admin if you need a new password.
02 Connect ESPN or Sleeper
On My Leagues, connect the league you are allowed to use. Berzerker imports league identifiers, scoring and roster settings, rosters, and standings when the provider returns them. Private ESPN leagues depend on the operator’s server-side cookies; sync can be delayed, partial, or unavailable.
03 Load rankings for that league
FantasyPros consensus rankings are fetched on the server and matched to the active league’s scoring (PPR, half-PPR, or standard) and roster rules (including superflex and tight-end premium when those settings exist). The public sample table is not this live board.
04 Draft with replacement value
Draft Room keeps tiers, position runs, roster needs, and who’s on the clock. Picks are judged against replacement value in your league — the next starter you would actually play — not a generic ranking average.
05 Move into the week
The same workspace opens weekly ranks, start/sit comparisons against league replacement, trade ideas, and a league report. You do not rebuild the league after draft night.

FAQ
Before you connect a league
Is Berzerker Fantasy Football free?
Paid access is a season pass priced at $29.99 for the NFL Regular Season (this season only). Invited workspace accounts sign in with a username and password. Connecting a league happens after you are signed in.
What does league-aware mean?
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 — scoring, roster construction, and available players in that workspace — not a one-size-fits-all list.
Where do the rankings come from?
FantasyPros consensus rankings are imported through a server-side connection and then matched to the scoring and roster rules of the active league. That is a research aid, not a claim that Berzerker is the most accurate board on the internet.
Can I use it without signing in?
Public pages explain the product, show a static sample table, and cover privacy and terms. Live rankings, draft tools, and weekly intel stay inside a signed-in workspace.
What are Premortem and JohnStradamus?
They are weekly editorial tools inside the workspace — a pressure-test (Premortem) and a prediction layer (JohnStradamus). They are not a public blog and not betting advice. Read the public explainers on Insights, then sign in to open them.
