Rest of Season Questions

I want to know who should I keep for the rest of the season so  I can either trade or drop them.

Pick 3 Safeties:
Harper
Chung
Y. Bell
Landry

Pick 2 CB:
Winfield
Woodson
WEbb

League Settings:

Tackle Solo 2
Tackle Assist 1
Sack 3
Interception 5
Fumble Force 2
Fumble Recovery 4
Defensive Touchdown 6
Safety 3
Pass Defended 2
Block Kick 3
Tackles for Loss 2

Thanks

This is a tough one. I'd go Landry, Harper, Bell. However, Chung is just as good. I'd go Webb and Woodson as Winfield's injury scares me a little.
