Positive-edge bet amount = (Edge% × 14) × (Projected Probability × 1.4) × Unit Size. Example: 5% edge at 60% probability = 0.68 units.

Add one or more WR/TE/RB route rules from any team, then select matching games. Multiple rules use AND logic.
WR Prop Distribution
Projected receiving yards now combine 1-Hi + 2-Hi + Man. WR pass attempts and CMP% are locked to the QB tab; ATT/DB uses the selected QB plus opponent defense model; WR route% can be manual or selected-week based; coverage rates are normalized to 100%; TGT/G is TPRR × projected coverage routes; and each coverage AY/G blends model output with selected actual AY/G.

RB Receiving Weeks
Select which RB coverage games should be used for route %, TPRR, targets, and receiving yards. 1-HI and 2-HI logs are embedded; Man is ready structurally and can be embedded as a file next.
Add one or more WR/TE/RB route rules from any team, then select matching RB games by week. Multiple rules use AND logic.
RB Prop Distribution
Rushing yards and receptions now sit side-by-side like the WR prop layout. Receiving production uses the blended 1-HI + 2-HI + Man formulas, and odds, edge, units, and dollar bet use the global Unit Size input.

Manual Odds Entry (Admin)
This is the only way odds get onto the site -- there is no paid live-odds API. Paste a week's matchups/spread/total, QB pass-attempts lines, and any of the prop boxes below (copied from a sportsbook site or a spreadsheet), click Parse, fix anything flagged red in the preview, then Save -- one click saves everything at once. This writes into the same cache the Week/Matchup dropdowns and "Fetch Live Lines" everywhere else on the site read from, so a save shows up immediately on the actual QB/RB/WR/TE Props tabs. Matchups format: one row per game, tab-separated -- Matchup ("AAA @ BBB") / Team 1 Spread ("AAA +3.5") / Team 2 Spread ("BBB -3.5") / Over-Under, each side's spread in its own column. The older single-column "AAA +3.5 / BBB -3.5" format still works too. QB Pass Attempts / RB Rush Attempts: Player / Number (these feed a model input directly, like Pass Attempts already does -- no odds needed). Anytime TD: Player / Price (a single yes/no bet, no over/under). Every other prop box (Pass Yards, Pass TDs, Interceptions, Completions, Rush Yards, Rush TDs, Receptions, Receiving Yards): Player / Line / Over Odds / Under Odds -- these feed the real bettable Line/Odds boxes on each tab, which drive the edge%/Bets calculations. Leave a box empty to skip that market entirely. Receptions, Receiving Yards, and Anytime TD are shared boxes covering RB, WR, and TE players together (same bet market regardless of position) -- no need to paste them separately per position. A header row is fine in any box -- it's skipped automatically. A row that can't be matched (wrong position for that box, ambiguous name, or a team not playing this week) is flagged red and simply left out when you Save -- it never affects any other row or player. You also don't need to re-paste Matchups every time: if this week's games were already saved, new prop rows still attach to them even with the Matchups box left empty.

This Week's Starting QBs
Starting QB = whoever actually has a posted Pass Attempts line for this week's game (a sportsbook only prices the real starter) -- not just the PDF roster's listed QB1, in case of an injury or a real depth-chart change since that guide was published. Proj Pass Attempts/Proj Dropbacks default to that live line (and the same ATT/DB equation the QB tab itself uses) -- shown as the placeholder text. Type a number into either box to override it; leave it blank to keep tracking the live default. An override here also applies on the actual QB Props tab the next time that QB is calculated (replacing whatever's in Pass Attempts there), and feeds the Route %/TPRR overrides below -- until you clear it again.

Skill Splits (Admin)
Admin-only -- not visible to visitors. Pick a team to see its real WR/TE/RB roster (from the current ESPN projection guide), already in projected-volume order. Reassign a player's slot or set their Blend Weight (Method A % vs. Skill Splits %, default 70) -- the "Set Blend Weight for whole team" box changes every row below at once (Apply to All), but you can still hand-edit any single player's box afterward. Pick "— (not playing)" as a player's slot to exclude them entirely -- their Routes/Targets/Rec/Yds/TD all project as a flat 0 (RB rushing, which isn't part of Skill Splits, is unaffected). Route % Ov = this player's Routes / QB Dropbacks (e.g. 85 for 85%) -- overrides Skill Splits' modeled Routes for them, using this team's Projected Pass Attempts/Dropbacks above. TPRR % Ov = Targets per Route Run (e.g. 18 for 18%) -- overrides Skill Splits' modeled Targets, applied against that player's own (possibly Route %-overridden) Routes. TPRR (all seasons), like ADOT (all seasons), is that player's real Targets/Routes from all on-site historical data (every season on file, including this season's games as they're added), shown only for reference next to the override -- it's never used automatically. ADOT (all seasons) is that player's real average depth of target from all on-site historical data, shown only for reference -- it's never used automatically. ADOT Ov defaults (shown as its placeholder) to the Skill Splits model's own number for that slot, not the real one; type a number (including the real one shown next to it, if you want to match it) to override it. Route %/TPRR/ADOT all flow through into Rec/Yds/TD the same way the model always computes them -- there's no separate Rec/Yds/TD override. Total Routes/Total Targets/Proj REC/Proj YDS/Proj TD on the right show the Skill Splits model's current result for that player (using this team's Projected Pass Attempts/Dropbacks and any overrides above, saved or not), so you can see the effect before saving. Tip: check the player's current projection on the WR/TE/RB tab first, then come back here to adjust it. Saving applies to every visitor immediately, not just this browser.
