Who should I start in FLEX spot?

Kenny Stills, Tevin Coleman, James White or Funches. Pick 1 WR and 1 RB to start in a FLEX positions… the team I am playing has Jarvis Landry and Jay Ajayi so I was leaning to playing my odds with Stills against Jarvis. I think I will end up going with Coleman if he is heathy for the game.
