Flex Help Needed, Pick one RB Non PPR

I'm kind of leaning him or Ivory.

MJD has a Thursday night game and he normally plays good versus Houston.

I think Ivory runs 25 times and the game stays close, since they play somewhat better at home. Murray had 3 TDs versus Oakland last week, but little yardage.

I think Bobby Rainey could go off to after doing fairly well versus Carolina.

Donald Brown and Woodhead are facing the tougher defenses but they are both 3rd down backs that can catch it out the back field.

any other opinions from the night shift?
