It's a simple game...
 

...except for KC or Arizona.

This week teams with a positive turnover differential were 13-2 (.866). (Buffalo and Jacksonville were even).

The two teams that lost with a positive turnover differential were KC and Arizona. Not good company.

However, keep that good ratio and more times than not, you'll win. With parity in the NFL the way it is, turnovers is the one stat that affects the game more than any other. The talent levels aren't that different and the coaching (from a strategy standpoint) is pretty even, but turnovers will be the deciding factor in most games.
