i think we do ..in Tony Pollard, - who ironically was doing a similar rover role at Memphis State.
But simply and plain , we just don't have that kind of OC in Kellen Moore.
If it were placed in McCarthy hands at the beginning, , that may be a different story.
RBs have been so greatly under-utilized and under developed under Kellen, imo.
If you see Pollard in motion, it's more as a mere decoy.
If that dude does to a KC Chiefs, he'd be game breaking factor in the pass game- once they've developed him the way Kellen did not , imo.
