How do you find value on a player prop?

Remove the vig from the over and under prices to get the market's fair chance, then compare it with your own estimate. If your estimate is higher, that side is priced in your favour.

Why do props carry more vig than game lines?

Props are lower-limit markets with fewer books pricing them, so the margin is usually wider than on a moneyline or spread. Shopping the price matters more, not less.

Reading a prop price

Props carry a wider margin than game lines because fewer books price them and the limits are smaller. Removing the vig first tells you what the market actually thinks, before you decide whether your own read beats it.

A projection is an estimate, not a prediction. If your number and the fair number are close, there is no bet — the honest answer on most props is a pass.
