Who to start, E.Sanders or C.Ridley?

12 Team half point PPR

Sanders vs Packers
Ridley vs Colts

My other WR start is M.Thomas and in my current Flex spot is M. Breida.
Who would you start?

I like the target share sanders is getting since he’s really the only option Flacco trusts and hes just force feeding him the ball and hes getting a lot of redzone looks. Also I think the game script will favor sanders.
