Successfully handicapping is just fantastically hard. The over and under is 31 and you bet the under in a teaser, bringing the total to under 37. You did all your proper handicapping , checking the weather, wind, past performances, etc. As a bonus, each team is using a second team quarterback. It'll probably end up 0-0.
Green Bay kicks off and Chicago fumbles the runback.
Now it's 14-0. Chicago changes its tactics and starts to pass on every down. You look back over your figures and see that the Bears have attempted thirteen passes in each of the last three games. So you figured it would be strictly a ground game, with the clock being eaten away, especially in this weather. Naturally, this is not an everyday happening, but sifting through tons of statistics can be frustrating when a certain happening causes the teams to adopt a different means to an end than what they had been doing.
