Which 2 LB to drop (DJ Smith, Freeman or Burfict)?

Current Roster:

LB - D'Qwell Jackson (bye wk 10)
LB - Ray Lewis (bye wk 8)
LB - Colin McCarthy (bye wk 11)
DB - Roman Harper (bye wk 6)
DB - George Wilson (bye wk 8)

Bench - Kam Chancellor (bye wk 11)
Bench - DJ Smith (bye wk 10)
Bench - Jerrell Freeman (bye wk 4)
Bench - Vontaze Burfict (bye wk 8)

Question #1 - Is it safe to start both Harper & McCarthy?  I really want to, but injuries & late game time have me nervous.  If i don't, which LB replaces McCarthy?

Question #2 - I'm going to have to drop 2 from my roster to cover some offensive byes.  Which 2 get cut?

Thanks

Start Harper and McCarthy. I'd start Burfict if McCarthy sits. Freeman and Burfict would probably get the ax, if I had to choose.
