Sometimes you look at a line like 49ers Vs Vikings and you can foresee the trap coming.... however it is easier to cast an air bet on the underdog then it is to put actually money on a team like the Vikings against the 49ers ...
I have noticed that alot of Air bettors seem to make good picks on this site, while the guys who bet real cash seem to not do so well...
airbettors like lakerboy and roxxxy tend to post large ml dogs because they literally have nothing to lose but everything to gain (e-glory/e-fame) if they hit.
