Drop a benched player for Breida?

I have Duke, Coleman, Latavius, and John Ross on my bench. The only ones I consider potentially “drop-able” are Ross and Murray. Yet, I still don’t think they’re completely worth dropping. Breida might not get the start, then he’s in the same position as Murray or Duke. John Ross may finally emerge this year, so I don’t know that I can drop him either. Any thoughts? Is Murray someone worth keeping this year? Rudolph gave him some high praise out of practice.
