The Start/Sit Desk

Start/sit calls that read the whole field.

A projection knows your WR averages 14 points. It doesn't know his quarterback tore a hamstring on Thursday and the backup is throwing. The Desk runs every starting slot through a context engine, adjusts the numbers, and rules START, SIT, or TOSS-UP against your best bench alternative.

The calls come with receipts — every signal names the actual humans involved. No black box, no vibes.

The interesting calls are the flips: paper says start, the field says sit.

SIT — PIVOT  WR
The arm feeding your starter might not go. His QB carries the Q tag — a hobbled thrower means shorter, safer targets.
TOSS-UP  RB
Two starting linemen down in front of him. Backup guards lose the leverage battles that spring long gains.
Soft front on the other sideline. The box defenders who close those holes are in sweats.
The Supporting Cast engine

Injuries around your players, not just to them.

DynastyOne syncs the entire NFL — offensive linemen, defensive backs, real depth charts, and the real schedule. So it knows things a fantasy app usually can't: your receiver's quarterback is out, your runner's line is held together with tape, the defense across from your tight end lost its best linebacker.

Each signal is tiered, signed, and folded into an adjusted projection. A downed corner boosts your WR; a gutted front seven boosts your RB — injuries only count for the positions they actually free up.

Position-aware mismatches, computed from charted starters — not headlines.

QB OUT — the backup is throwing your WR1 the ball now. Major downgrade · volume may survive; efficiency rarely does.
Line in tatters: LT and RG both ruled out. Moderate downgrade for the runner behind them.
Green light through the air: their CB1 and nickel are down. Targets funnel wherever the injury is.
The Defense Ladder

History says feast. Or famine.

Every NFL defense, ranked 1–32 on fantasy points actually surrendered to each position — built from real weekly box scores, not narratives. Facing the second-most-generous defense against wide receivers? The ladder says so, in plain English, right on the call.

“They've been a turnstile for WRs all year” — with the per-game average to prove it.

1st
31.2 /gm to WRs

Kickoff weather

The sky is part of the matchup.

For every outdoor game, DynastyOne pulls the forecast for the actual kickoff hour at the actual stadium. Howling wind kills deep balls and field goals; a soaked track drops pass volume; a deep freeze stiffens everything. Domes stay silent — as they should.

Kickers get hit hardest — exactly like real life.

27 mph gusts at kickoff — the ball won't fly straight. Wind is the one weather that truly moves fantasy scoring.
75% chance of rain on your QB's game. Wet games lean run-heavy and drop pass volume.
Matchup Edge Intel

Know their sideline better than they do.

The matchup page reads both rosters: your lineup leaks and theirs, their walking wounded, the projected edge, and market value on the field. Because DynastyOne sees all your leagues at once, it even flags double agents — opponents starting players you're starting in another league.

Intelligence only a multi-league command center can produce.

War Pigs p112 PROJECTED EDGE +14 Gary's Goons p98
Their lineup is leaking 9.6 projected points. Two of their starters are on bye and they haven't noticed.
Double agent: their WR2 is your FLEX in Office Bloodbath. Every catch cuts both ways — plan your sweat accordingly.
Roster Scout & Power Rankings

A front office for every roster.

Positional grades against your league's average. Waiver targets at your weak spots, ranked by projection and league-wide add velocity. Trade ideas with rosters that mirror yours — your surplus for their surplus — with real market values on both sides.

Power rankings blend projection with points scored, and call out who's rising and who's been lucky. A lineup optimizer itemizes every point you're leaving on the bench.

Advice in a scouting voice — zero AI cost, all signal, works offline on game day.

Lineup optimizer: +17.3 projected available. START Trey Lockhart 14.4 → over Cole Winters (out)
Waiver target at TE: 11.8 projected, +24.6k adds league-wide. Free in this league, filling your weakest grade.
Precap emails

A briefing before every kickoff window.

Thursday night, both Sunday slates, Monday night — before each window opens, DynastyOne emails you a precap: who's out, who's questionable, which slots leak points, and the Scout's best pivot for each. Lineups get locked before kickoff, not mourned after.

Cross-league watchlist, season form strips, and an intel feed round out the war room.

SUNDAY AM PRECAP · WEEK 3
Fix now: your WR is a scratch in Dynasty Degens. Slide the bench stud in — a real chance at points beats a guaranteed zero.
Scout's corner: your opponent benched their best RB. Projected edge grows to +11. Lock it before the early window.
