NFL Same-Game Parlay Stacks — Correlation, Measured

Same-game parlays pay less than the multiplied odds because the book prices correlation — this page measures it. Every QB + top receiver pair, graded by how often both legs actually cleared their lines in the same games versus what independence predicts, with the correlation boost printed. Where DraftKings posts full-game lines on the pair, we show the naive multiplied price next to our measured joint rate at those exact lines. Free, no signup.

What it does

FAQ

Which same-game parlay legs actually hit together?

QB + his No. 1 receiver is the classic: our measured pairs cleared both their lines together in up to 50% of shared games when independent math predicted 34%. The stacks page prints that joint rate for every qualifying pair, from real game logs.

Why does DraftKings pay less for a same-game parlay?

Because correlated legs win together more often than the multiplied odds imply, the SGP engine reprices the combo below the naive multiply. Our page shows both numbers — the multiplied price and the measured joint rate — so you can see the size of the shave.
