What would change the answer

0.5 points a game is the entire case. The market restates it every week, and a line that moves moves the order with it.

The draft market is the half that is missing: when live drafts hold these two again they can order them differently from the projection, and this page will follow the drafts rather than the market-based projection when they do.
