Hillman (back) is rotating behind both starter C.J. Anderson and rookie Devontae Booker, the Broncos' official site reports.
When the Broncos signed Anderson to a long-term deal and drafted Booker, the presumption was that Hillman would be lightning to Anderson's thunder while Booker waited in the wings. Now Hillman finds himself battling Booker and undrafted free agent Kapri Bibbs for a role on the team, according to head coach Gary Kubiak. Bibbs, who saw more touches than any other back in the preseason opener, offers a younger, cheaper option as compared to Hillman, who would count just $500,000 against the cap if cut. The fact that a Hillman v. Bibbs scenario is playing out in camp shows just how far last year's team leader in rushing has fallen out of favor.
