It's no secret that Vegas totals and spreads can be helpful when making fantasy football decisions -- especially in daily fantasy games.

Unfortunately, as professional NFL handicapper Warren Sharp has pointed out, Vegas' primary goal is not to set the most accurate lines -- Vegas' goal is to make money, and they do that by encouraging public action on a particular side. What does that mean?

Let’s say Vegas opens the line on a game with Team X favored to beat Team Y by 7 points. If 80% of the public money coming in is in favor of Team X against the spread but Vegas still does not adjust the line, that demonstrates that either there is sharp money on Team Y or that Vegas feels confident about Team Y against the spread. Either way, by examining how Vegas is moving lines in comparison to where the public is betting, we can potentially gain an edge when making lineup decisions.
