Let me see if I can get this right:
As it stands right now, signs point to Hillman earning more carries/opportunity based on preseason play. How much that will eat into CJ remains to be seen, but history of this system and Kubiak points to the use one main back.
If CJ goes down, we won't know how things will pan out, but history/system/Kubiak trends point to the same -- the next RB becoming the focal point for the running game. At this point, based on preseason play and ability to fill the role, either Ball or Hillman can do it, but performance leans towards Hillman being the guy.
As such, Hillman is the better handcuff right now. While we won't know until we know, the way Denver runs the ball, the way the system and Kubiak features one back, it will be CJ being the primary back with the others helping to spell/utilized on 3rd downs; if he's injured, we think Hillman has the better long term shot as both next guy up and a guy who has earned some more play regardless.
Do I have that right?
