Some people think bookmakers are trying to predict the most likely final score of the game. But they are actually trying to pick the exact number that will cause equal dollar betting on either side of the contest, then they pocket the 10% vig.
Somebody is failing hard at predicting that number and adjusting it on the fly.
Do they have software to analyze the bets , so that they would adjust the point spread, so as to avoid this sort of situation?
I have a feeling that somebody, somewhere, is having a tough meeting today, to explain how the house lost so much money on the bets.
