Need help at flex

Looking at 2 different teams:

One is 12 team ppr made the mistake of starting Davis thinking he was going to pop off with Hayden out but the options are - Amari Cooper, Alex Collins, Rex Burkhead, Corey Coleman?

Other team is a 12 team ppe (points per everything) double qb and I had Collman come off IR so had to make room. I dropped Brate (have Gronk) and Booker with the news of Fournette I picked up Ivory. For my flex here do you think ivory or Coleman?
