You know how you can look at Matchbook the night before a game or early the day of and there's, say $4,000 available to bet on team A at -150. -150 is a better line then most sportsbooks are offering at that point, but there's still a 7 cent vig differential at matchbook. Do people really ever bet it? Why would they when they could obviously wait for the line to get better(most MB lines settle at 1 cent juice) or make their own better offer?
