RB2 Troubles (Bonus Flex Question)

With Joe Mixon out for the next two weeks plus, I really don’t know what do at RB2 in PPR. Missed out on Gio due to Waiver Priority and almost all the good RBs or backups are picked up(I know, should use FAAB)

Royce Freeman, Tarik Cohen, Theo Riddick, Latavius Murray or Jordan Wilkins? I have Royce lined up right now, but strongly considering Riddick. The Lions are bad and he has had 19 targets in two weeks.

Thoughts?

(Also, have 4 WR’s starting, 2 WR/2 Flex, would you start any of those RB’s ahead of Green(obviously not), Hogan, Funchess or Cole)
