Andrew Luck and ROS

So, when do you guys feel it would be time to just give up on Luck and stream for the season? I hate holding on to two QB’s but does Luck still have the arm talent to be worth keeping? (PPR League)

Other options for this week would be:

Dalton @ ATL (ATL defense is missing everyone)
Tannehill @ NE
Flacco @ PIT ( Great matchup)
Manning vs NO (Not an Eli fan, but the Saints defense is a sieve)

Would you keep Luck or drop him?

Roster is: (Would you drop someone other than Luck?) We start 2 RB - 2 WR - 2 Flex

Luck
Gurley - Mixon(IR Slot) - R. Freeman - Cohen - Riddick - Murray - Yeldon - Ivory
Green - Hogan - Funchess - Cobb - Cole
Ebron - Engram

Basically just looking for a lotto ticket while Mixon is out. Grabbed as many backups as I could with the amount of injuries happening to RB’s.
