Who would you start for flex ppr

In my league w have WR, WR/RB, and Flex.

For sure starters are
QB: Matt Ryan
RB: CJ Anderson
RB: Mike Gillislee
WR/RB: Amari Cooper
WR: Doug Baldwin
WR/TE: ???

Flex options: Kyle Rudolph, Danny Amendola, Rashard Higgins

I also could swap one of my WR and go with another RB such as Chris Johnson or Chris Carson who are on my bench. Need help picking since Sam Bradford may not be playing today for Minn. so I’m not sure if Rudolph would be the best option.

Any opinions to help make my decision would be appreciated!
