Underhill: The Saints believe their running game has the potential to be as good as anyone's

That depends. Is it 2nd and long? If so, you're gonna pass it. :hihi:

Really, it will be refreshing if our running game can keep the defense fresh.

It all works togegher. Running the ball a little more does help keep the defense fresh. Having depth helps keep the defense fresh. Having a fresh defense keEPS games in reach which allows you to run a little more... which helps keep the defense fresh and so on.
