NFL Pool Question

[closer]

For the last 2 years I participated in an NFL Pool. Every week you get a card with 15 games on and it and the betting lines from the newspaper that day (Thursday). The person who picks the most games right for that week wins a % of the pool for that week. If there is a tie it carries over.

At the end of the season it pays for the top 3 spots based on best overall record for the season.

I was wondering if anyone had a strategy I could try. I usually do decent but I never got in the top 3.

I usually read this forum for picks to help with my own analysis but with 15 games it gets a little tough to know which side to take.

Any ideas for a strategy/system?

Thanks Guys.
