The Facts: Following up on a previous item. ... McKinnon tore his ACL before the start of the season and has no guaranteed money left on his deal, so it’s hardly out of left field to think the team might part ways with him while moving forward with newcomer Tevin Coleman, Matt Breida and Raheem Mostert. On Thursday, HC Kyle Shanahan said that’s not the plan.
Diehards Line:Shanahan went on to explain the depth at the position is not a problem and didn’t rule out having all four running backs — Mostert is a core special teamer — active for games. McKinnon still has rehab work to do as well and Coleman’s presence allows that to continue without worries about an exact date that he’ll be ready. That outlook could change as other roster needs and/or offers from other teams pop up this offseason, but, for now, the Niners say that four is not a crowd.
