Chark, Gallup or Malcolm Brown?

Start two between these three, picked up Malcolm Brown on waivers when Gurley was declared out, thinking about flexing him, but not sure whether to play him over Chark or Gallup if at all.

My RBs are Bell and carson so not gonna play him over those guys

Brown is scary to me. If Gurley does suit up, even limited. That hurts Brown a lot. And I think they’re going to lean more on Henderson personally.
