    • The line class matches the retrieved base rate almost exactly: Washington is a road favorite of 3.5 points in a Big Ten game, and that class has covered at 63.4% since 2021.
    • Washington is the better team by record (5-4 vs 3-6, and 2-4 vs 1-5 in conference), consistent with why they are favored on the road; this supports but does not add much beyond the base rate.
    • Signal against Washington: starting QB Demond Williams Jr. is questionable, plus two other defensive contributors questionable and a running back doubtful — quarterback uncertainty is the single largest downward adjustment.
    • Signal for Washington: Michigan State's availability report is worse in volume — 10 players out including defensive starters, plus a doubtful running back and questionable corners — which partially offsets the Washington QB concern.
    • Recent form is ambiguous narrative: Washington lost a tight game to Penn State while MSU is coming off an emotional rivalry win over Michigan, which can precede a letdown; treating this as weak signal only.
    • Netting a modest downgrade for the QB-questionable risk against the heavier MSU injury toll moves the estimate slightly below the 63.4% base rate to about 60%.

    What would change it: Confirmation before kickoff that Demond Williams Jr. will not play (or that Michigan State's questionable defenders are all cleared) would move this estimate several points down (or up).
