NFL Big Board & Rankings Tool

Three views — Big Board · Positional · Depth Charts
Switch from the tab bar at the top of the page
Big Board
Positional
Depth Charts
Big Board — your full overall ranking in one list, sorted by your personal rank. Drag any row to reorder. This is your source of truth.
Positional — same rankings split into QB / RB / WR / TE columns side by side. Tier breaks you set on the Big Board carry over at the correct positional rank slot.
Depth Charts — team-by-team view. Shows each player's depth chart position alongside injury and suspension flags and your personal rank.

Draft Mode
All / QB / RB / WR / TE — filter the Big Board to show only that position.
Multi-Select — checkboxes appear on every row. Check multiple players, then move them as a group to a target rank slot.
Set Tiers — enter tier mode. Click between any two players to draw a tier break. Breaks show as labelled dividers (Tier 1, Tier 2…) and carry into Positional view at the correct positional rank.
Add Player — add a custom player at a specific rank; everyone below shifts down. Leave rank blank to append at the bottom.
Edit Player — turns green when active. Click any player row to edit their name, position, team, age, or flag them as AVOID. Press Escape or click the button again to exit edit mode.
Reset to Default — resets your entire board back to the pre-loaded default rankings. This cannot be undone.
Export Rankings CSV — downloads your current board as a CSV file.
Import Rankings CSV — upload a CSV to replace your current board. Must match the expected column format.
Draft Mode — turns blue with a pulsing dot when active. Click a player's checkbox to mark them drafted — they dim and get a strikethrough. Must be turned on explicitly to prevent accidental clicks while dragging.

Player rows — what each column means
Columns: RNK · POS · PLAYER NAME · TEAM · AGE · BYE WK · WK 17 · STATUS
Tier 1
1 RB Saquon Barkley PHI 28 BYE 7 WK 17 ✓
Tier 2
2 WR Ja'Marr Chase CIN 25 BYE 12 AVOID
3 QB Lamar Jackson BAL 27 ✓ Drafted
RNK — your personal rank for that player.
AGE — player's current age. WRs 29+ show a warning flag in the Notes column.
BYE WK — their bye week number.
WK 17 — whether the player has a Week 17 game (relevant for best ball scoring windows).
AVOID — your personal do-not-draft flag. Set via Edit Player. Visible in Big Board and Positional view.
✓ Drafted — player marked taken in Draft Mode. Row dims and name gets a strikethrough.

ACTIVE SLOT AUTOSAVES
Save up to 5 separate boards — useful for different formats, contest sizes, or stack strategies.
The active slot autosaves every time you reorder a player. You never lose your work.
The active board slot syncs to the Chrome extension — whichever slot is active is the board the extension uses during a live draft.
Sign in to save boards to your account so they sync across devices.
💡
Make sure the correct board slot is active before you enter a draft room. The extension reads whichever slot is currently active.

⚙️

Assist — your best available players from your Big Board, in rank order. Filter by position (All / QB / RB / WR / TE). Already-drafted players are removed automatically as picks are made.
Roster — your current team as the draft progresses. Reads directly from the draft room page.
Board — your full ranked board with a search bar. Search by player name, team, or rank number.
Alerts — flags players on your board worth knowing about (age warnings, injury/suspension status, etc.). The badge shows the count of active alerts.
Always click "Save & Sync to Extension" before entering a draft. The status strip at the top of the sidebar shows your board name and how many players are loaded — if it's blank or showing 0, sync again.

Portfolio Snapshot
How exposed are you to each player across all your teams?
Saquon Barkley
72%
CeeDee Lamb
58%
Ja'Marr Chase
33%
Bar chart of every player across all your drafted teams. Higher % = heavier exposure. Use this to spot concentration risk before draft season ends.

Player Combo Lookup
How often do two or more players appear on the same team?
Type two or more player names into the combo search box. The tool calculates the percentage of your teams where all of those players appear together.
Use this to check if you're over-correlated on a QB + WR stack, or to find combinations you've been underusing.
