yeah, we don't mean to throw 50 times, it just happens. It keeps happening because they think you just hand the ball off and get 5 yards without dedicating practice time and without having a scheme that helps the run game. Nope just hand the ball to a power back standing flatfooted in shotgun behind an OL in 2 point stances and see what happens. What happens is nothing, because that's what you put into it.
Even in the glory years of Bettis, the run game often got 3 yards per carry early. That's how it goes. A strong run game is body blows that add up. Bettis would get stronger as the defense got weaker and by the end it's unstoppable.
Too many of these new school OCs just don't understand that a run game is not about tricking people. It take commitment in practice and in games.
Maybe it was Lev Bell who ruined some of the steeler coaches. He could create runs out of nothing but few RBs can do that. Same with Antonio Brown in the passing game. You could throw a bunch of short ones and he'd eventually turn one into a big play.
So now you have an offense throwing short expecting them to become big plays based on a WR making big run after catch, and an afterthought run game hoping the RB can just make plays happen with minimal blocking.
