Who to start in my flex this week?

My options are Randall Cobb, Rob Kelley, Thomas Rawls, or Corey Davis

I like Cobb but Davante Adams is my WR2 already. But I do feel like that game could be a shoot out.

I like Cobb as well, especially if its PPR. If it’s standard I don’t think it would be horrible to maybe go with Davis or Rawls, I’d like to see how Rawls does first though.
