Running Back/Flex help

[dberry120]

I think I'm pretty set at QB and WR's with Rivers, Jennings, Steve Johnson, and Lloyd. However, Im weak with running backs and I have 2 RB spots and 1 flex spot in my league to fill. For my RB's on my team I have Mathews, Addai, Keiland Williams, Dixon, Morris, and Goodson. I also have Garcon as an extra WR. Which 2 RB's do I start and who do I put in my flex spot? Garcon or a 3rd RB? This is a PPR league, but not points per carry.

Addai, Goodsen, Garcon best options based on PPR.
