Bet on NFL lines are oftentimes set based on public perception. That public perception comes from many different sources and reactions. If you are getting involved in NFL betting you should know that the odds are made based on many different factors but nothing is as important as what the public thinks.
Bet on NFL lines are not always what they appear. First, there is the general perception of the two teams involved in a game. Teams with stellar championship credentials such as Pittsburgh and New England will carry with them something of a “tax” against the weaker teams as the oddsmakers will know that the public will be hesitant to take a lesser team, even with extra points as they bet on NFL games.
