Who to play at flex, Standard league

Hey all, I have received lackluster production from my flex so far and I need some advice on who to play between Mixon, Kupp, Crowder and Lee? Let me know what you think, thanks!

I’d go Crowder in a potential shoot out. Mixon will eventually start for Cincy but you have to wait it out

That’s what I was thinking, I feel like this of all weeks would be the one that Mixon will get an opportunity but it’s risky.
