I am not a stats man as any stats can lead down blind alleys, in my experience.
Some years ago I devised a method which would tell me how a team were playing the basics, regardless of the results. Although these didn't take into account turnovers, red zone scoring and final scores, it does help weeding out lucky and unlucky results.
There are always going to be odd results in the NFL but if you bet teams that are playing fundamentally well, taking in consideration the spread, you can pick up some nice winners.
I allot 1 pt for qualifying in the following catagories.
First Downs- 20 or more
Yards per play- 5.0 or more
Rushing Yards - 100 or more
Rushing attempts- 30 or more
Completions- min 18
Comp att- min 30
Completions must be 60% for them to count.
Defensive numbers are a mirror image.
Example: New England last 6 games
(A) NY Jets Off-2 Def-4
(H) Jacksonville 3 5
(H) Miami 1 6
(A) Indianapolis 2 4
(A) Houston 4 5
(H) Dallas 0 6
Now reading these figures, that the Defense has carried this team and only once in 6 games has the Off been above average is no earth shattering news this time of year, but during the season its amazing how they are overlooked.
It could be also said that going into the play-offs, against supposedly better opposition, New England has no margin for error.
To sum up, I only use these figures as a guide, factor in the spread, injuries, weather and a bit of experience, hey presto, a bet.
Sorry got lost, what was the question
