Cooper or pooper? Flex PPR help

I had Cooper on my bench this week (like any sane FFBer would) and thankfully still won. Im fighting for wins from here on out because Im on the cusp of not making play offs (3-4 in 10 man league). Can I play Cooper moving forward or at least this week? Ive got a few clutch guys on bye. PPR league. Also, Im playing the guy I need to beat to keep my PO seat so semi must win. This league has a few at top, a few at bottom and 5 people that are at same wins and only a few points separating.

Due to bye weeks, I only have Buck Allen, D. Parker, D. Funchess and A. Cooper and need to play 2 at flex.
Was planning on Cooper and Funchess likely.
Thanks guys.
