Flex help .5ppr: Breida, Anderson, or Sanders?

My opponent had Allen Robinson go off more than I expected, so I have to have someone who’s going to ball, at least, equally. My main concern is Breida’s usage with Coleman and Mostert. Should I be? Or is Shanahan going to let him run?

(No TE League)
