Is there any method to our RB by committee madness?

We seem to swap backs randomly, there's no real pattern. It's not by series, or down and distance, or even who is playing well.

It seriously feels like they rotate them for no reason and with no purpose.

I miss the days of having 1 primary back we fed. Coffee, Ingram, Richardson, Lacey, Yeldon, Henry...

They had help but they were the man and got fed. I think any of our backs could be the man if we'd let them. Nobody can get any sort of rythym going.
