Start sit WR2 and Flex

Full PPR Championship.
Already have Hopkins, McCoy, Collins (14.10 points on Saturday), Delanie Walker locked in.
As for WR2 and Flex I have to choose between

Golden Tate @ CIN
Josh Gordon @ CHI
Carlos Hyde v. JAX
Demarco Murray v. LA Rams
Devin Funchess v. TB

Any suggestions much appreciated!
