I suggest that all of you remember that you are giving the vig (sometimes big vig) in most of these cases. Taking a team at -150 is giving 3/2 odds. In most cases, that is too big. Check the Vig before you go diving in. Failing to count the vig is a big reason why some people think they made money during the season and then find out that they actually lost money. If you ignore the vig, you are NOT a very good gambler.
