What does a -2.1% edge mean?

A negative edge of -2.1% means the price (+310) is worse than fair value (+319). 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 24.4% 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 23.9%, which converts to fair odds of +319.

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

AI breakdown

Verdict: This Cardinals win total boost offers fair value at best.

Value: The AiOddsLab rating of 51/100 suggests a neutral proposition with no inherent edge against fair odds.
Market context: the matchup original or consensus odds, it's impossible to compare the boosted price to its true market value.
Status: the matchup is no notable injury signal for the team.
Social: the matchup data is available from Reddit to gauge public sentiment.
Risk: This is a single-leg future with inherent longshot risk, as it depends on a specific team performance outcome over multiple games.

Smart insight: The outcome is highly sensitive to the Cardinals' early-season schedule and overall team performance. Similar profile: This falls into the category of early-season team win total futures, which often carry high variance due to limited initial data. Counter-case: The uncertainty of early-season NFL performance for any team makes predicting exact win totals difficult and prone to significant variance. Live context: the matchup any news regarding team health or depth chart changes closer to the season.

Recommendation: Pass.

How this bet was graded

Grade B · 51/100 · Better Off Passing

ARI Cardinals 2 Wins After Their First 5 Games at +310 on DraftKings: 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. B (51/100) 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 B-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.
