Help me set my WR2 and Flex... Half Point PPR

Half point PPR I need to pick a WR2 and a Flex out of this… Who should it be?

I like corey davis and cooper kupp. Davis has high upside and kupp has a safe floor

Yeah thats what ive been leaning towards myself… I have Fournette in my flex right now, If he plays im not sure i wanna play him… So i was curious who you guys would play in the flex instead
