Only DraftKings quotes this game so far, so there is no second number to compare it against. Books further out post one at a time; this fills in as kickoff gets closer.

Player props
The books haven't posted player props for this game yet — normal this far out. The archive is already watching for them: the moment a price appears it is captured, kept forever, and becomes loggable here.
When they land you'll get the same book you get on the game lines — closing-line value, a letter grade and a good-bet verdict on every prop you log. No projections: our prop model failed its own pre-registered calibration gate, and we don't ship numbers that failed.
Every point above is a price we observed and stored, with the time we saw it. Nothing on this page is a prediction, a rating, or a recommended bet.

Across 6,967 regular-season games since 1999, 24 of 28 spread rungs with a usable sample had a 95% interval containing 50%. In other words the number itself has never been an edge, at any rung, in twenty-seven seasons. What it is good for is knowing which numbers are expensive to cross — and a rung holding fewer than 30 games is shown greyed rather than dropped.
