AI breakdown

Verdict: This single-leg boost offers unknown value due to missing original odds.

  • Value: The value cannot be determined without the original odds.
  • Market context: No comparative odds are provided, so market assessment is impossible.
  • Status: the matchup is no notable injury signal.
  • Social: the matchup is insufficient social data to assess.
  • Risk: As a single-leg prop, it avoids multi-leg parlay variance.

Smart insight: the matchup knowing what "achieve something" means, it's impossible to identify what moves this bet's EV the most. Similar profile: the matchup player props vary widely in their actual win probability and often have juiced lines. Counter-case: The unspecified nature of the event "achieve something" against CHW makes accurate assessment impossible. Live context: the matchup lineups near tip-off.

Recommendation: Pass.

How this bet was graded

Grade B · 53/100 · Better Off Passing

We graded Willson Contreras vs CHW at +290 on FanDuel by comparing the offered price to a vig-free consensus of the wider market. The ticket centers on Willson Contreras. The bet earned a B grade (53/100), which we label "Better Off Passing".

The headline number is edge versus fair: -2.26%. That figure is the long-run expected return per dollar staked, assuming the market consensus is an unbiased estimate of true probability. Because we couldn't fully match this market across other books, fair value here was derived from the host book's own posted line — treat the edge as directional rather than precise.

Fair odds calculation

Fair +299 · Implied 25.1%

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, and average the resulting no-vig probabilities. The averaged probability for this outcome lands at 25.1%, which converts to fair odds of +299.

Compared to the offered price of +290 (a +0.0% move from the original line), that produces an edge of -2.26%. In plain English: if the market is right about the true probability, you'd expect to lose about 2.3 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 -2.3%, you're paying a premium versus the consensus fair price of +299. 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 -2.3% edge mean?

Edge measures the gap between the price you're getting (+290) and the fair price implied by the broader market (+299). A negative edge of -2.3% 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 25.6% 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 25.1%, which converts to fair odds of +299. The offered price of +290 is then compared against that fair line to compute edge.

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

Sportsbooks usually advertise the percentage lift over their own original price, which they set with house margin built in. Our grade compares the offered price to a vig-free market consensus, so a "+50%" advertised lift can still grade poorly if the original line was already inflated, and a small lift 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 B-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.
