For the Chief's game I believe the books took a position on SD for the spread and while that worked out for them these favorites winning, in many of the games, including KC is not good from the book's perspective.
It's game by game for the spread, to be honest, there are different situations in the market.
But bettors weren't buying upset moneylines today and they are emboldened by their winnings.
The books take the hit. Let's just look at one game.
Let's assume there's one bettor on each side. Now I know many think books want to split the money, but I've shown that's not true. But let's asume it's 50/50 among the betting population.
SBR Odds reports Pinny reporting Pit -267 to Den +232. Let's also keep it simple with the standard (albeit suicidal) degen betting method...Guys walks in lays his $267 on Pit to win $100. His weed connoisseur cousin in Colorado says hell naw and puts his $100 down to win $232.
So what happens for the book? He's collected $367 and if Pitt wins Pinny has to pay it all out, but if there's an upset, Pinny only pays out $332, keeping 35 bucks.
Never mind that the public slammed the favorites anyway, for the most part, not giving the books a chance to take in enough on those dogs. They aren't worried about that, not one bit.
Like I first said, those bettors are emboldened and the books know they will give it all back and then some.
