THE FOURTH DOWN PROTOCOL

We don't let one ignored notification cost you the week.

You choose how far Fourth Down should go. When a catastrophic lineup error remains unresolved, the alert gets harder to miss.

  1. 01
    Push notification“Higgins is inactive and still starting.”
  2. 02
    EmailYour risk, deadline, and best replacement.
  3. 03
    Text messageOne tap back to the lineup decision.
  4. 04
    Phone call + voicemailBecause taking a zero is no longer acceptable.

You control the channels, quiet hours, and escalation level. Fourth Down only raises the alarm for genuinely costly mistakes.

YOUR GM AFTER THE FIRE DRILL

First it prevents disaster. Then it helps you win.

Fourth Down knows your roster, league, available players, and preferences—then turns the week's information into clear decisions.

01

Set the lineup

Get a roster-aware start/sit recommendation with the matchup, risk, and upside behind it.

02

Catch injuries

See urgent lineup risks before players lock, including whether you have a viable late replacement.

03

Win waivers

Find available players who improve your actual roster—not another generic top-ten list.

04

Pressure-test trades

Understand what a trade fixes, what it exposes, and how it changes the rest of your season.

YOUR WEEKLY GM BRIEFING

Advice that remembers you're still the owner.

Hey, Mr. Doe.
You're the team owner, so it's your call. Here are my recommendations for Week 1:

Start Addison over Higgins, place a waiver claim on Corum, and hold your defense. The Addison move is urgent; the others are optional upgrades.

Optimize for upside. What changes?

Keep Higgins for now, add Iosivas as insurance, and I'll check his status again 90 minutes before kickoff.
