No ATS bucket beats the vig

Plenty of fans believe certain situations offer a significant edge, home underdogs and huge favorites chief among them. Across thousands of games, every situation sits at around 49-50% against the spread (ATS), below the 52.4% needed to beat the standard -110 juice.

Home underdogs cover at 49.4%, roughly the difference between a coin flip and a 51/49 favorite. Home favorites sit at 49.1%. Huge favorites cover at 49.0%. The largest deviation in the whole set, conference games at 48.9%, still lands under the break-even point. Set the actual cover rate against break-even and the gap comes out around 3.4%, about the difference between a 50/50 toss and a 53.4/46.6 favorite.

The line already prices in public biases, which is why the large-sample numbers land where they do. Even the smallest deviation in the set, the 50.2% cover rate for huge underdogs, vanishes once the vig comes out.

• Home underdogs cover at 49.4%, roughly 3% below the break-even point
• Home favorites cover at 49.1%, also below the break-even point
• Huge favorites cover at 49.0%, offering no edge

Every ATS bucket sits below the 52.4% needed to beat the vig. So be wary of anyone selling you home dogs covering 55%, or any claim cut to that shape; those numbers are likely built on incomplete or misleading data.
