What does a +73.9% edge mean?

A positive edge of +73.9% means the price (+700) pays more than the fair price (+360). Over many identical bets, that gap is your expected return per dollar staked.

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

No. The market still implies about a 12.5% chance this hits at the offered odds. A +EV bet pays more than its true probability warrants — most +EV bets at long odds still lose individually.

How are fair odds calculated?

Sportsbook prices on the same market are de-vigged and averaged to estimate a true win probability. Using the available market price, we estimate 21.7%, which converts to fair odds of +360.

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

Books quote lifts vs their own original line, which already includes margin. We compare the price to a vig-free consensus, so an advertised lift can still grade poorly if the underlying line was inflated.

Should I bet every bet that grades well?

Grading is a price-quality signal, not a guarantee. Even a A-grade bet can lose. Size within your bankroll, account for correlation, and don't chase results.

AI breakdown

Verdict: This parlay has an eye-catching offered price with a significant increase from its original listing!

Value: the matchup a precise market consensus isn't available, the offered price of +700 represents a substantial 77.8% price lift compared to the original +350, which is definitely appealing.
Market context: The Kansas City Chiefs Moneyline leg has a fair price of -131, which is a solid starting point for this parlay, but Patrick Mahomes Over 250.5 Passing Yards doesn't have a directly comparable market consensus.
Status: the matchup is no notable injury signal for any listed player.
Social: the matchup social data available for insights.
Risk: This is a 2-leg parlay, and as with any parlay, multi-leg parlay variance adds a layer of risk, especially with one leg lacking a direct market comparison.

Smart insight: The value of this bet heavily relies on the implied probability of Patrick Mahomes exceeding 250.5 passing yards, given the Chiefs are already favored on the moneyline. Similar profile: This is a classic player prop paired with a team outcome, often seeing its biggest payouts in higher-scoring, competitive games. Counter-case: The biggest risk lies in the uncertainty around the Patrick Mahomes passing yards total, as there's no comparative market to gauge its true fair value. Live context: the matchup lineups near tip-off for any last-minute changes.

Stake suggestion: the matchup stake.

How this bet was graded

Grade A · 85/100 · Lottery Ticket

Chiefs Moneyline & Patrick Mahomes Over 250.5 Passing Yards at +700 on Bet365 (2 legs): we couldn't match this slip to enough comparable market prices to compute a trustworthy consensus fair value, so no edge % is shown — anything we'd print would just echo the book's own vig. The grade leans on price lift vs the original (+77.8%), leg count, and variance. Treat it as directional.

Frequently asked questions

Why isn't an edge % shown?

We couldn't match this slip to enough comparable market prices to compute a trustworthy fair value. Rather than show a number derived from the offered price itself (which would just echo the book's vig), we leave the edge unstated. The grade still reflects price lift vs the original, variance, and confidence.

Does the grade still mean something?

Yes. A (85/100) is built from the price lift, leg count, variance, and any verified context signals — it's directional. Treat it as a sanity check, not a precise EV figure.

Should I bet every A-grade ticket?

Grading is a price-quality signal, not a prediction. Even an A-grade ticket can lose. Size within your bankroll, account for correlation between legs, and use Inside Angles above to spot factors the price hasn't absorbed yet.
