Flex decision, please help!

Who should I FLEX this week in a MUST WIN playoff deciding matchup… M.Ingram (NO), M. Evans (TB), Funchess (CAR) or M. Gordon (LAC)?? Standard League Format.

I am currently starting Howard (CHI) and Perine (WAS) in RB spot… And D.Adams (GB) and R. Anderson (NYJ) at WR.

Any and all help would be MUCH appreciated… Thank you in advance!
