RB who do i start in a standard league?

Waiver wire is thin at RB position. I picked up Duke Johnson, the available RB’s are Mike Davis, T.Y, Bibbs, Ivory, or Jacquiz. Do I start Duke or pick one of these RBs?

Who is t.y? I would not start duke, he will disappoint lol

Think about picking up mike Davis. Carson is questionable

Yeah I have the sleeper app so I should get notified before anyone else in my league and will probably do that if Carson if ruled out
