What Makes an NFL Same-Game Parlay Different
A standard parlay pulls from separate games. A same-game parlay — SGP — pulls every leg from one NFL game, which means the outcomes are correlated. A running back getting 90 rush yards and the favorite covering the spread aren't independent events; books factor that in when they price the slip. That correlation cuts both ways: legs that reinforce each other can
produce better-than-expected payouts, while conflicting legs — like a blowout win and an over — can pull the slip apart fast. Building an SGP means reading the game script, not just stacking props at random.
