Devin Singletary?

Trying to fit Devin into my starting lineup. 3 guys for 2 spots. Sony, Kerryon or Devin. I love Sony’s matchup, but he was so bad vs Pitt. I’d probably take Kerryon out. Thoughts?

Hes a perfect Flex spot imo. im not 100% sure that i would start him over Kerryon or sony.

I have Kamara. One of these 3 would be for a flex.
