I can definitely see this happening for 1 big reason. Coaches generally worry about pass pro more than anything in regard to rookie rbs & something I rarely see mentioned when people are falling all over themselves talking about Harvey is the fact that he's not good in pass pro. In fact, he was one of the worst backs in college football last year in that regard. It's only gonna take Nix getting blown up one or two times for the coaches to get gunshy on Harvey being in there on passing plays.
