Should I start Chris Godwin or parker Washington in my flex?

I managed to snag Chris Godwin off waivers after someone unexpectedly dropped him for Michael Mayer, and now I need help deciding whether to flex Godwin or Parker Washington to help me dig out of an early hole. AJ Brown only gave me 5 points while my opponent's kicker put up 7, and facing a dangerous lineup (Joe Burrow, Saquon Barkley, Bijan Robinson, Rashee Rice, DeVonta Smith, and Chig Okonkwo), I need maximum upside from my flex spot alongside the rest of my core (Jalen Hurts, Omarion Hampton, Travis Etienne, Amon-Ra St. Brown, and Sam LaPorta).
