Need Flex decision help

Need help deciding for week for flex option.
Full PPR and 0.3 per carry.

Royce Freeman has a great match up and is proven to be the goal line back.
Allen Robinson has had the targets, just hasn’t hit pay dirt yet but has a great match up as well.
I also have Chris Godwin, but I think this match will slow down for TB some.

I’m stuck on who to play, need to make the right choice since I’m 0-3.

Rest of roster:
QB: Russel Wilson
RB: Melvin Gordon
RB: Kerryon Johnson
WR: Julio Jones
WR: Stefon Diggs (did be good last night)
WR: Cooper Kupp (did be great last nigh!)
TE: Gronk Smash
Flex: Need help deciding!
D: Da Bears

Bench: J Wilkins, B Mayfield, Q Enuwa, Chris Godwin, TJ Yeldon , Allen Robinson and Royce Freeman
