Drop/Add Chase for Kelley?

PPR
Drop Chase Edmonds for Joshua Kelley?

Current RBs: Zeke/Benny Snell/James White/Chase Edmonds

Seems like you have 2 choices… do you want the back that will be a low end RB1/high RB2 if the starter goes down(Edmonds) or the guy who is consistent but is most likely a low end RB2/High RB3(Kelley)? Regardless I would be terrified to start any of these options as my RB2
