Why are the Saints so bad at running the football?

I don’t know the root cause but clearly things have been heading south for awhile.

Kamara hasn’t averaged 5.0 yards per carry in any of his last 22 games.

Kamara has had 1 (ONE) game where he averaged 5 YPC in the last 3 seasons!

He has yet to exceed 80 yards rushing in a game this season.
