G. Jennings or Lloyd? Dez or Britt, Mcfadden, B.Brown?

Two different teams first one is PPR
I am leaning Jennings just because Nelson looks to be out again, but that weather in Chicago probably won't help.


Second is non PPR:

This is for my flex. Currently, I have Brown as my RB2, McFadden as my flex and Britt as my WR2. So would you insert Dez in any of those spots if he can go? I included Brown, but I think I will start him over Mcfadden if I moved Dez to flex and Mcfadden to Rb2.


Thanks for the help.
