Two markets from the same books. The season-totals market: a full-season over/under already prices in what has happened, so the line minus the player's stats to date is what the books expect from here. The weekly prop market: this week's projection, the deepest and most frequently re-priced market there is.

Season totals move slowly, so the rest-of-season number averages the two: the season line's remaining pace and this week's projection, times games left. A player with no line this week uses the season leg alone. Players whose season lines have been pulled, usually injuries, drop off rather than being guessed at.
