NFL betting during the month of September can be very tricky and dangerous for gamblers. NFL online betting in the first month of the regular season is full of unknowns as teams have, to one extent or another, changed players, coaches, assistants, strategies, etc. NFL betting gamblers often get into trouble during September because the NFL betting lines and public perception is based on last year’s results, preseason media hype, and the inability to fully judge the merits of each team's offseason moves and any new schemes.
At the start of the NFL betting season, most of the preseason analysis is based on the previous year's results. History has shown that you just can’t make money betting last year’s results in NFL betting. Look what happens every season to previous Super Bowl teams. They almost always struggle against the NFL betting pointspread. Everyone believes that the Super Bowl champs will continue to have success, but rarely does that happen in NFL betting the following season. The Super Bowl runner-up is an even worse bet in NFL betting the following year.
Preseason media hype is another trap that many NFL online betting gamblers fall into. Usually the media or NFL betting chat boards will all come up with a so-called “clever” or “sleeper” pick that is supposed to take everyone by surprise. The problem with that is, of course, that it is no longer a surprise once it is exposed to the masses and the “word gets out.” It is very difficult, admittedly, in NFL online betting to accurately judge the various offseason moves that each team made. So the best thing to do is to be cautious during the first month of the season and don't overreact or overreach on anything you see early in the NFL betting season.
