What RB to start? D Johnson, Mike Davis or J McKinnon?

Question

I lost Barkley last week and I need to figure who to replace him with. I drafted David Johnson and I picked up McKinnon off waivers last week and got Mike Davis this week. My gut is saying Davis or McKinnon. Hard to trust Johnson against Pittsburgh 

Answer 1

Close with tough matchups for Johnson and Davis, it close, but give Johnson the start even against Pittsburgh.

Answer 2

You lost Barkley for the season.  Pack it in Bro.  None of those clowns is going to replace him.
