Out of 15 games this week the winning team either won outright as a dog or covered the spread as a favorite. Only game that was an exception was the Saints/Panthers game where the line jumped from -3.5 to -10 after Drew Brees was hurt so it was an exception to the rest. Also the Colts won but didn't cover the spread.
Point is you first need to pick a winner. If you are good at it then either lay the points if you want the favorite to win or bet the dog ML. Taking the points is a waste of money and energy. Also do not bet teasers because they are sucker bets.
