Flex dilemma - A.Hernandez, Daniel Thomas or Santonio Holmes

[democrew]

Hi All... have a pretty solid team with McFadden, Megatron and Sproles starting, I need to start 1 in flex - Daniel Thomas RB, Aaron Hernandez TE or Santonio Holmes WR in PPR league. Who should I start?

(Fortunately they are all games which start later)
