Yup. I really think whether or not Murray is moved into the starting spot, with Felix filling more of a flex role like he used to, all depends on how Murray plays in the next few games that Felix is out.
If he can keep his stats to a good 80/90+ yds with a TD, I think he'll get half and half once Felix comes back to see what one another can do on the field with a timeshare.
Best comes out the starter, second gets the flex role.
