End of bench Chase

My 3 main RB’s are EElliott, CLH and JMixon

But sitting on the end of my bench is Chase Edmonds who did ok in week one.
I am now trying to decide it i should keep him, swap to Tony Pollard as a backup for EElliott, or drop him for someone like JKelley or Benny Snell who are still sitting unclaimed.

Any advice?
