How this bet was graded

Grade F · 26/100 · Hard Skip

We graded 11-Leg Same Game Parlay in Spurs @ Knicks at +14218 on FanDuel by comparing the offered price to a vig-free consensus of the wider market. The bet earned a F grade (26/100), which we label "Hard Skip". The grade combines four sub-scores: price value (how the offered odds compare to fair odds), market agreement (how tight the consensus is across books), historical context (how similar bets have priced in the past for NBA), and risk (parlay length, correlation, and volatility of the underlying markets).

The headline number is edge versus fair: -2.20%. That figure is the long-run expected return per dollar staked, assuming the market consensus is an unbiased estimate of true probability. A positive edge means the price is generous relative to fair value; a negative edge means it is tighter than fair. Edge is a statistical expectation across many identical wagers, not a forecast for this specific ticket.

We do not bake personal opinions, news, or model predictions into the grade. The score reflects price quality only — whether FanDuel is paying you more or less than the rest of the market says the outcome is worth. That keeps the grade auditable: if you re-ran the same numbers tomorrow with refreshed lines, you'd get a comparable result.

Fair odds calculation

Fair +14540 · Implied 0.7%

Fair odds represent the price you'd see in a perfectly efficient, zero-margin market. To compute them we pull current prices from the available sportsbooks on the same market, strip out each book's vig (the overround built into both sides of the line), and average the resulting no-vig probabilities. The averaged probability for this outcome lands at 0.7%, which converts to fair odds of +14540.

Compared to the boosted price of +14218 (a +0.0% move from the original line), that produces an edge of -2.20%. In plain English: if the market is right about the true probability, you'd expect to lose about 2.2 cents on every dollar staked, on average, across many bets of this exact shape.

Why the market disagrees

The wider market is pricing this outcome tighter than FanDuel's line suggests is reasonable. With an edge of -2.2%, you're paying a premium versus the consensus fair price of +14540. The bet can still win — odds are not destiny — but the price embeds a built-in disadvantage that compounds across repeated wagers. Shopping the same market at a sharper book, or waiting for the line to move, is usually the correct response.

Frequently asked questions

What does a -2.2% edge mean?

Edge measures the gap between the price you're getting (+14218) and the fair price implied by the broader market (+14540). A negative edge of -2.2% means the price is worse than fair value. You can still win the bet, but the long-run math is against you.

Does a positive edge mean the bet is likely to win?

No. Edge and win probability are different things. The market still implies roughly a 0.7% chance this hits at the offered odds. A +EV bet is one that pays more than its true probability warrants — most +EV bets at long odds still lose individually. The edge only shows up across many similar wagers.

How are fair odds calculated?

Fair odds are derived by taking sportsbook prices on the same market, removing the bookmaker's vig (the built-in margin), and averaging the resulting no-vig probabilities. For this bet we used the available market price to estimate a true win probability of 0.7%, which converts to fair odds of +14540. The boosted price of +14218 is then compared against that fair line to compute edge.

Why does this grade differ from the sportsbook's advertised boost?

Sportsbooks usually advertise the percentage lift over their own original price, which they set with house margin built in. Our grade compares the boosted price to a vig-free market consensus, so a "+50% boost" can still grade poorly if the original line was already inflated, and a small boost can grade well if it pushes a fair price into +EV territory.

Should I bet every bet that grades well?

Grading is a price-quality signal, not a guarantee. Even an F-grade bet can lose, and you should size stakes within your bankroll, account for correlation between legs, and consider your own information about the matchup. This tool helps you avoid bad prices — it doesn't replace judgment or responsible bankroll management.
