DynastyOne

The Fantasy Football Command Center

DynastyOne

Fantasy managers burn Sunday morning bouncing between five tabs — league apps, injury feeds, weather, depth charts, and hot takes — and still start the wrong player. DynastyOne pulls every league into one dark-mode command center and turns raw projections into start/sit calls that read the whole field. Media Lion designed and built the product end to end: brand, interface, data engine, and marketing site.

The Challenge

Turn Sunday Chaos Into One Clear Screen

The brief was ambitious: unify a manager’s entire fantasy football life on one screen, then make it smarter than the projections everyone already has — syncing multiple platforms, modeling the real NFL, and earning trust with every call.

  • Five Apps, One Sunday
    Managers juggle Sleeper, ESPN, injury feeds, weather, and social — then still miss a scratch. Everything had to live on one screen.
  • Projections Miss the Context
    A number knows your receiver averages 14 points. It doesn’t know his quarterback tore a hamstring on Thursday. The app had to price in the context projections ignore.
  • Injuries Around a Player, Not Just to Him
    A downed lineman or a banged-up secondary quietly moves fantasy value. Modeling that meant syncing the entire NFL — depth charts, offensive lines, and defenses.
  • Every Call Needs Receipts
    Managers won’t trust a black box on Sunday. Each recommendation had to name the actual players and reasons behind it — no vibes.

The Solution

One Command Center, Four Engines

Services Provided
Toolkit Used

We shipped DynastyOne as a fast, dark-mode Vue application backed by a context engine that syncs every league and the whole NFL. Four connected engines turn that data into plain-English calls — always warm before kickoff.

  • The Start/Sit Desk
    Every starting slot runs through a context engine that adjusts the projection and rules START, SIT, or TOSS-UP against your best bench alternative.
    1. Context-adjusted projections, not raw averages
    2. START / SIT / TOSS-UP verdict on every slot
    3. Surfaces the flips — paper says start, the field says sit
    4. Receipts on every call: the actual players and reasons
  • The Supporting Cast Engine
    DynastyOne watches injuries around your players — the linemen, corners, and depth charts a fantasy app usually can’t see — and folds each into an adjusted projection.
    1. Full-NFL sync: O-lines, secondaries, real depth charts
    2. Tiered, signed injury signals
    3. Position-aware — a downed corner lifts your WR
    4. Computed from charted starters, not headlines
  • The Defense Ladder
    Every NFL defense ranked 1–32 on the fantasy points it actually surrenders to each position, built from real weekly box scores.
    1. Per-position rankings from real box scores
    2. Plain-English matchup context on each call
    3. “A turnstile for WRs” — with the per-game average
    4. Kickoff weather folded into every outdoor game
  • Matchup Intel & Precap Emails
    The matchup page reads both rosters and flags double agents — opponents starting players you’re also starting elsewhere. Before every kickoff window, a precap email lands.
    1. Both-roster matchup edge and lineup leaks
    2. Cross-league double-agent alerts
    3. Precap emails before each slate
    4. Waiver, trade, and lineup-optimizer scouting

Don't just take our word for it.

  • Door Guard engaged Media Lion to bring our website into the 21st Century, and Jeff Seals did not disappoint. After landing a large contract with a Fortune 500 company, we needed an easy-to-use, interactive site that let their sales force create their own quotes and place their own orders — a huge productivity improvement for Door Guard.
