As the Lions’ RB competition unfolded, there weren’t many players who separated themselves. Injuries to Jermar Jefferson and Mohamed Ibrahim didn’t help, and the sudden retirement of Justin Jackson came as a surprise. When Craig Reynolds got the bulk of the carries in the first half of the preseason, it felt like you could pencil him in as RB3. However, the Lions’ initial 53-man roster has just two true running backs: Montgomery and Gibbs.
Not that many were worried about either option coming off the field after they spent so much monetary and draft capital on the two, but it's still a relief to know they're not part of a three-back rotation. It sounds as if Reynolds could be back on the team, as he's not subject to waivers. There will likely eventually be an RB3 on the roster, but it's clearly an afterthought for the team.
