Coleman hold vs upside stash

I’m curious to get the views here. Current RBs Gordon, Fournette, Henry, Coleman, Clement, Kerryon in my 12 team standard league. What’s the general view in holding a guy like Coleman as a potential flex starter here or picking up say a Dixon, Aaron Jones, L. Murray or even a Wilkins who has a chance at being the starter either by weaker competition ahead (Dixon/Jones) or injuries (Jones again, Wilkins and maybe Murrary).

Just curious based on my roster with 2 studs and a better flex in Henry than Coleman is it worth using the depth to take more of a shot here on one of these? Or just hold Coleman as a solid RB with RB1 upside or trade power if Freeman goes down? The Freeman owner isn’t keen on a trade right now.
