The 15.5-point spread combined with a 50/50 moneyline split creates a cushion play. Getting 15.5 points in a game the market prices this tight is the structural edge.

Spread of 15.5 points — double-digit spreads in football cover only ~47% historically, creating inherent dog value. Road favorites must overcome roughly 3 points of home field baked into the line.

Overround at just -100.0% signals an unusually efficient market — edges here are small but more likely to be real. This is a low-vig environment where the math is reliable.
