Johnson is a subpackage specialist for the Bills -- a firecracker off the bench who runs designated routes in passing situations to the point that he's almost like a RB-WR hybrid to the Bills rather than a true RB2 behind starter James Cook. It's worth making the distinction because while fantasy investors often look to the RB2 on any given depth chart as the handcuff pick for the starting running back in question, Johnson probably isn't the handcuff pick even though he's the RB2. There's a role for Johnson but not RB3 Ray Davis when Cook is healthy, but if Cook isn't available then most of Cook's tasks are better suited to Davis. Johnson will remain a constant presence in the Bills offense, but if more opportunity arises it still might present a scaling opportunity for Johnson's otherwise strong per-snap numbers.
