Start Perriman over Cooper for diversity in PPR? (1 Viewer)

I am a slight favorite in my PPR Finals matchup and am considering diversifying my lineup.   

Given that Zeke is one of my RBs and Dak may be less than 100%, do I diversify away from Cooper and risk starting Perriman in PPR?   

I am leaning Cooper (dance with who got you here). Team is as follows:

Lamar

Zeke, McCaffrey

M. Thomas, Cooper or Perriman

Goedart (or Howard)

Ekeler at Flex

I like Perriman(can't believe I said that) for the shear volume.  cooper is a great option too.  

Cooper didn't get you there last week. He has only gotten double digits 2 of the last 5 weeks and only 1 TD over that span. 

Winston is playing for his job and he is playing significantly better. Evans and Godwin were both legit WR1 all year. He has to throw it somewhere.

I'd stick with Cooper.

I'd also go Howard over Goedert, as he has a higher ceiling, and could benefit from the WR injuries on Tampa just as much as Perriman does.
