The tell: Spread moved >=1.5pt, total moved >=2.5pt, or moneyline implied win probability moved >=3pt.

Division rivals know each other well, keeping divisional games close; a moneyline underdog the market still prices as competitive (not a near-pickem, not a longshot) covers that implied probability at an elevated rate.

The tell: Divisional game AND the moneyline dog's implied win probability is in [0.3, 0.45].
