Need help with a couple pieces for optimizing my lineup to hopefully take the ship to the house!
Appreciate any and all feedback, will help back! 0.5 PPR        START 2 RB, 2 WR, 1 FLEX

RB - Gurley @ SF (tough matchup… second guessing)
RB - Chubb vs BAL (tough matchup but he torched them earlier this season)
RB - Mostert vs LAR (Dallas just torched, feeling confident despite late fumble last week)
WR - Edelman vs BUF (tough call... not confident here)
WR - DJ Moore (new starting QB for the Panthers, not confident here either) Bench:

WR - Diggs vs GB (like playing Russian roulette?)
WR - Chark @ ATL (banged up)
RB - Mack vs CAR (sweet matchup)
WR - TY Hilton (sweet matchup)

Waivers: 

Could attempt to pick up Perriman (TB) if no one claims him.

Thoughts? Roll with my studs or make changes?
