Flex conundrum. Full PPR. Tilting hard

Full PPR:

Damien Harris, Khalil Herbert, Latavius Murray, or Alex Collins (ONLY if Carson is out)

I also have these FA options: Mecole Hardman (I have Mahomes), AJ Green, Amon-Ra St. Brown, or maybe a dart throw w Van Jefferson.

Obviously scraping the bottom of the barrel here lol.

Pretty much in the same position Kamara and Patterson on bye leaves me Murray Damien harris and K. Herbert is on the waivers. I think Im gonna start Murray they have used him at the goal line and lamar had a little bit of a fumble issue down there so really just hoping he falls in the endzone. Maybe twice lol but yeah hard dart throws.

I need it as a rb but you being able to flex I might take a shot at Amon-ra or Green
Green has been alright and a redzone threat
Amon-ra theres no one elseā€¦ Detroit fan here too (not a thrilled one) I can see him getting 8-10 targets if he gets the td hes gonna have a great week
