Tennessee has made its mark this season. So have Cincinnati and Detroit for different reasons.
But one of the main storylines of this season is the success of the passers.
Entering Week 9, there are six quarterbacks with a 100.0 passer rating, which is unprecedented.
There have only been eight seasons in history with more than one quarterback posting such a rating. Now granted, the weather is just starting to get cold, and the ball is just beginning to get slippery, and the numbers probably will drop some. But where they are now is at all-time highs.
Just look at the evidence.
