IDP waiver wire

We saw nice week 1 performances by Sean Washington, Sean Lee, Chancellor, and Burnett. I want to add 2 of them and drop William Moore after his disappointing week 1. How would you rank these 4 from the wire for ROS? Thanks.

My lineup:
LB-Derrick Johnson, Ryans, D'Qwell Jackson
DL-Cole, Kiwanuka (LB eligible)
DB-Bell, Moore
D Flex-Von Miller

IDP scoring is 1.25 per tackle, .75 per assist, 5 per sack, 5.5 per INT, 5.5 per fumble force, 3.5 per fumble recovery, and 2 per pass defended.  

I would go with Chancellor, Burnett, Lee and the Washington. I like Chancellor and Burnett this year. Lee looked good but does have some competition for reps.
