SharpModels is a benchmark built only from team ratings: it doesn't see injuries, rest or lineup news. When it and the market disagree, the market often knows something.

Closing lines

This game was played before we started collecting prices (22 October 2026), so we have its closing prices only, from DraftKings, BetMGM and bet365: no line movement or player props. A price can differ from the book's own by a cent or two.

Margin: how much a book builds into its moneyline (its implied chances add up to more than 100%). Lower is fairer; the lowest is in green. Under Best, the margin if you took the best price on each side.

Every price change, book by book: tap the table icon by any selection, line, team total or player.

Best spread and total weigh the line against the price: a better line is worth paying a little more for, most of all onto key numbers (half a point is worth more where games often land). Moneyline: simply the best price.
