Drop MJD for either L Taliaferro BAL or B Sankey TEN?

I'm currently in desperation mode with RBs. I have Peterson, D Williams, Moreno, and Ingram all hurt/suspended. I have Murray and K Robinson in play, but we play 2 flex spots so I can start up to 4 RBs. I also have Crowell, but he is on a bye week, plus all reports I have read have indicated Ben Tate will be back after Clevelands bye weeks which will reduce Crowells fantasy value. This is a Dynasty PPR League, so I am thinking about picking up Taliaferro or Sankey. If you were in my shoes, would you hold on to MJD or Crowell? Or would you drop one or both for the other two?
