Keenan Allen, Corey Davis or Someone Off of Waivers?

I have Keenan Allen and Devante Parker currently slotted in as my WRs this week. Don’t really want to play Allen because of the match up against Jacksonville, but all I have to sub in for him is Corey Davis or Martavis Bryant. I could also jump on waivers and acquire Jermaine Kearse. This is a 12-team, full-point PPR. What is your advice?
