Help guide me, fantasy board overlords

Here is my predicament this week vs the #1 player in our 12 man PPR league:


QB Cam Newton (have a waiver claim for Tyrod Taylor that would go through tomorrow)
RB Doug Martin
RB Buck Allen
WR Michael Crabtree
WR__________
TE Travis Kelce
FLX_________
DEF Jaguars
K Will Lutz

Bench:
WR Mohammed Sanu
WR Kelvin Benjamin
WR Desean Jackson
WR Davante Adams
RB Frank Gore
RB Alfred Morris
TE Cameron Brate
Tom Brady and Laveon Bell have bye weeks

So, who will be my WR2 behind Crabtree, and who should get the flex spot? Sanu has been pretty solid in PPR. KB scares me because I don't know if he will see the field at all since it's the first week with his new team. Desean Jackson averages 11 points, but the Bucs have struggled. Davante Adams lost Aaron Rodgers and his production dropped off tremendously the one game without him.

Do Gore, Morris, or Brate qualify as a flex piece over any of my WRs?

And should I drop Cam for Tyrod? Take away Cam's 2 20+ point games and he hasn't gotten more than 13 since week 1. He also just lost his #1 WR to Tyrod's team.
