Player props: markets that settle on one person

A player prop settles on an individual's recorded production rather than on the game result. Most are two-way over/unders on a counting statistic, set at a half-number so a push is impossible; some are yes/no questions such as anytime scorer. The official league statistic at the book's stated cut-off is what settles it, not the broadcast graphic.

The line is a projection of one player's workload rather than a forecast of a contest, so it moves on information that never touches the game line at all — a backup ruled out changes a workload prop and leaves the spread where it was. That is the whole reason the market exists as a separate object rather than a derivative of the spread.

Void rules are narrower than people assume. A player scratched before the event usually voids the bet and returns the stake; a player who takes any part at all and then leaves injured usually does not, and the bet stands and loses. Some books also treat 'did not start' differently from 'did not appear'.

And that is the trap. Combined-statistic props — points plus rebounds plus assists, receptions plus yards — settle on a composite the official feed may revise after the whistle. Books state a settlement cut-off, and a stat correction after that cut-off does not reopen the bet, which surprises people who checked the box score an hour later.

What to do with it. Read the void rule and the settlement source for the specific statistic before betting it, not the general house rules page.
