I just don't think he'll be given the role without even more injuries.
I have a sort of working theory and that working theory is that Andy Reid is going to use whoever is on the field when the offense is effective and will attribute that success, in part, to the back in the backfield. So it's entirely possible (to me) that Hunt is kind of washed but still wins the job through pass protection and knowing where to be in the offense for dump offs and check downs. If you take this line of thought seriously or find it compelling, then it might not take an injury for him to win the job.
I think he's washed, personally, but I'll bet he runs a 4.75 at this point in his career and he's a bull. I don't see much separating (including CEH) all of these sort of plodding backs that KC has right now. Reid cutting Ingram shows that they're not valuing speed so what do I know?
But the whole efficient offense determining who plays in the backfield isn't so ridiculous; or it is, and it's just a thought I had.
