Player Props & Game Lines Research
Player props and team game lines — same research-card idea, different signals.
Game Lines
Research team moneyline, spread, and total markets
- Venue and head-to-head records in plain language
- Best odds per side with split-market ranges when books disagree
- Opposing team or direction context on every card
- Relevant injuries for both teams in the matchup
Prop Market Research
What's on a player prop card
Every prop research card — NBA, MLB, or NFL — shows the same sections.
Lean & Best Odds
Strong Lean Over/Under plus the best line and price we found across tracked books.
Split Market
When books post different lines on a prop, the card shows the min and max line range.
Market Read
Opportunity, Worth Watching, or Potential Pass — with a short explanation of why.
Hit Rates
Recent over/under percentages for the leaned side. Tap to expand the other side too.
Home / Away Clears
How often the player has cleared this line at home vs. away, with tonight's venue highlighted.
Relevant Injuries
Injury notes tied to that player or prop — when we have data for the matchup.
Game Line Research
What's on a game line card
Research moneyline, spread, and total matchups with the same card structure across NBA, MLB, and NFL.
Team or Direction Lean
Moneyline and spread: team name. Totals: Over or Under — or No Clear Lean.
Records That Drive Lean
Venue and head-to-head windows in plain language. Last-N overall is context only.
Head-to-Head Context
Matchup-specific history against tonight's opponent when sample is 3+ games.
Best Line & Odds
Moneyline price, spread line, or total line plus juice from the best available book.
Opposing Side
Expand the other team (h2h/spread) or the other direction (totals) for full context.
Split Market
H2H: price range per team. Spreads/totals: line and price ranges when books disagree.
Relevant Injuries
Injury notes for both teams in the matchup — when we have data, not a full league report.
Market Read
Three signals on prop cards
Prop Market research only — Game Lines use team or direction lean states instead.
Opportunity
Trend and price both look favorable based on our analytics. Our strongest read on the card — not a guarantee.
Worth Watching
There's a lean, but trend and price aren't strong enough yet. Keep an eye on it — don't rush.
Potential Pass
No strong lean, or the price doesn't support action. May not be worth a look right now.
How It Works
30 seconds of research per card
Two research modes. Different signals — same scan-and-decide workflow.
Prop Markets
1
Check Over/Under lean
See which side weighted hit rates favor — or whether the market is still too mixed.
2
Check best line & price
One highlighted line and price for the leaned side from tracked books.
3
Expand context
Open hit rates, home/away clears, and injuries — then check Market Read for readiness.
Game Lines
1
Check team or direction lean
Team name for moneyline/spread. Over or Under for totals. Or No Clear Lean.
2
Read venue & H2H records
Plain records like "Won 6 of last 10 away games" or "Covered 6 of last 10" — what actually drives the lean.
3
Compare sides & injuries
Best line/odds, expand the opposing team or direction, and check relevant injuries for both teams.

FAQ
Sports Betting Research FAQ
Prop Markets
What does Opportunity mean?
Trend and current price both look favorable based on our analytics. This is the strongest of our three reads — not a betting recommendation or guarantee.
What does Worth Watching mean?
There's a lean, but trend and price aren't strong enough yet. Keep an eye on it — don't rush.
What does Potential Pass mean?
No strong lean, or the price doesn't support action. The card suggests this one may not be worth a look right now.
Is this an odds board?
No. BettorIndex is a research tool. Each prop card shows one best line and price for the leaned side, sourced from BetMGM, DraftKings, FanDuel, and Fanatics.
What does Books Disagree mean on props?
When tracked books post different lines on a prop, the card shows the minimum and maximum line — a Split Market range. It does not change which side trends.
What are Relevant Injuries on props?
Injury notes tied to the player or matchup for that prop — not a full league injury report. Shown when we have data.
Game Lines
What are Game Lines?
Team-level research cards for moneyline, spread, and total markets across NBA, MLB, and NFL. Each card shows a lean based on recent venue and head-to-head results, plus best available odds.
How does moneyline research work?
We combine each team's venue win rate and head-to-head win rate when enough history exists. Cards show records like "Won 6 of last 10 away games." Last-N overall is shown for context but does not drive the lean.
How does spread research work?
Same idea as moneyline, but using cover rates instead of wins. Cards show "Covered X of last Y games" and surface the best spread line and price.
How does total research work?
We combine home-team, away-team, and head-to-head clear rates for the Over and Under directions. The lean is Over or Under — not a team pick.
What does Split Market mean on game lines?
When books post different numbers, the card shows the range. Moneyline: price min ↔ max per team. Spreads and totals: line and price ranges. Split Market does not change the lean.
What does the opposing team section show?
When a lean exists, the leaned team's stats and best price are up front. Expand the opposing team's section (h2h/spread) or the other direction (totals) for full context.
What are Relevant Injuries on game lines?
Injury notes for both teams in tonight's matchup — not a full league report. Shown when we have data, same idea as props but scoped to the game.

What is BettorIndex?
A sports betting research tool for NBA, MLB, and NFL. Research player props and team game lines with trends, leans, and best available odds. A decision aid — not a sportsbook or picks service.
Which sports and books are supported?
Prop Markets and Game Lines cover NBA, MLB, and NFL. We track BetMGM, DraftKings, FanDuel, and Fanatics. Not every market will have all four books available at the same time.
How does BettorIndex score research?
Props: weighted recent hit rates compared to implied odds, which feeds the Market Read. Game lines: a simple sum of venue rate plus head-to-head rate when enough history exists (totals add both teams' clear rates per direction). Injuries and split markets are context — they do not change game-line lean direction.
