It's like this:
If our running game was good, our offense would be exponetionally better. Yards per play would be way, way up with just an average running game.
If our best RB played, our passing game would be worse and our offense would suffer (because JF can't do the things the system requires him to do well enough in the passing game).
I think Babers goal this season was to install his system, results be damned (and the growth that the players would gain in it, as well as showcasing things for recruiting purposes). And I think it was the right choice. He's playing the long game.
Basically: His system in year one with no running game > Not a full install of the system using a better RB

So next year a great deal depends on ED's health. If he can go and Rex is a capable backup, we get to RS Tommy D. (Best case scenario, IMO). I think one of the true freshman RB comes in (I like Markenzy Pierre) and wins the job as #1, Strickland moves to the slot or to S.
So to complete the circle: If our running game was good, our offense would be exponetionally better.
