What this is, and what it is not

These are our strongest market-specific props, chosen on the best combination of recent form, season baseline, the matchup itself, and the line actually available. The Lab's card is a separate five-pick slate selected across every market, and it is graded on the public record.

Where the record lives: the Lab's public record starts Sep 25, 2026, the card and the boosts together, with every pick and every loss on the results page. Each prop above is frozen with the exact price and book shown from the moment it was published. These angles are not on that graded record; the card and the boosts are.
