Why are the Saints so bad at running the football?

And as soon as he gets a tweaked ankle/pulled hamstring late in the game when it doesn't matter, the know it all fans on here will be screaming that he shouldn't have been on the game.
The point is to rest them/sub them out when the game is won. Not when we are down, tied game, or close game. AK41 has said that he wants to be the guy we lean on. Go rewatch his press game pressers. Plus, injuries are part of the game. Can’t play scared and I know the players don’t play scared
