Exactly right. It's always difficult to prepare and know what is going to happen in that spot when the starter is injured or not ready. Reguardless of it being RB. However, in this instance- the line can't block well for Davis if they aren't sure if he'll be carrying the ball because every back is different and runs differently. It's also a distraction and hurts the mental attitude of a team not knowing if the guy they need to count on will be ready or not.
