Start/Sit RB Help!

I have 4 valuable RBs that could start. 0.5PPR.

Barkley v. TB
Chubb v. DET
Montgomery v. BAL
D. Williams v. DAL

Currently I have:
Barkley, Chubb and Montgomery starting. With williams on the Bench.

Thought?

It doesnt get any easier next week. I have D. Henderson coming back from bye.

With Vita Vea going to be out for TB defense, their run defense will be softer than normal.

I, personally, would leave Williams on the bench and keep what the starters you have.
