A good excercise to start analyzing the point spreads
Here is an idea that will help you get started thinking about which games are over/under valued in the coming week. Look at each game, but do not look at the point spreads! See each team's record, who they have played against, the defensive, and offensive rankings and make your own judgement of what the spread should be. If you follow the NFL weekly spreads, your estimate will probably be really close in most games and not more than 5 points in most. Make a note of those games whose spread are the farthest from what you think they should be. Then, watch my picks and see if one of them coincides. These games will probably be your best bets.
