Can't decide on my flex

If it was not a ppr leauge I would start Ben Jarvis green Ellis.

Mike Williams of sea vs nyg with Charlie Whitehorse at qb will be boom or bust Whitehorse has a big arm

Steve Johnson vs chi. He's been a big play guy but does it end this week?

Bjge vs Cleveland he's the steady hand but whitehead gets all the catches.

I can also pick up Derious heyword bay if he's a better option
