What does a -2.2% edge mean?

A negative edge of -2.2% means the price (+1000) is worse than fair value (+1025). You can still win, but the long-run math is against you.

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

No. The market still implies about a 9.1% 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 8.9%, which converts to fair odds of +1025.

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 D-grade bet can lose. Size within your bankroll, account for correlation, and don't chase results.

AI breakdown

Verdict: This parlay boost offers poor value due to significant implied correlation risk and an unmatched leg.

Value: The boosted odds of +1000 are substantially worse than the -115 combined market consensus, indicating negative expected value.
Market context: The first leg alone, BUF Bills to Win Super Bowl LXI, has a fair price of -104, suggesting the market expects the second leg to be significantly correlated and overpriced by the boost.
Status: the matchup is no notable injury signal for any relevant players.
Social: the matchup data is available from Reddit to gauge public sentiment.
Risk: This is a two-leg parlay, inherently carrying multi-leg parlay variance, exacerbated by one leg having unmatched odds.

Smart insight: The value of this bet is most sensitive to the implied probability of Josh Allen winning Super Bowl LXI MVP if the Bills win, which is severely discounted by the boost's pricing. Similar profile: This is a "team to win championship plus main player MVP" parlay, a category often priced with heavy correlation baked in, frequently overvaluing the MVP leg. Counter-case: The primary reason to fade is the poor value compared to the combined market consensus, implying a heavily juiced line on the outcome. Live context: the matchup lineups near tip-off.

Recommendation: Pass

How this bet was graded

Grade D · 44/100 · Better Off Passing

Is This The Year? Back the BUF Bills & Josh Allen to win Super Bowl LXI at +1000 on FanDuel (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 (+0.0%), 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. D (44/100) 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 D-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.
