change my lineup?

I'm in a 14 team league - 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.  My IDPs are:

LB-Derrick Johnson, Ryans, D'Qwell Jackson
DL-Cole, Kiwanuka (LB eligible)
DB-Bell, Moore
D Flex-Von Miller
BN-Ray Edwards

Notable FAs are Dawan Landry, Patrick Peterson (there are points for return yardage), Chancellor, Morgan Burnett, Glover Quin, Chris Hope, Sean Weatherspoon, Brandon Spikes, Kavell Conner, Andre Carter, Lamarr Houston, and Kyle Williams. Do you think I should make any changes? Thanks and BTW, this is a great site!

No. Your team looks set. I would normally recommend Chancellor, but this is a sack-heavy scoring system.

I would agree with the guru here, your lineup looks pretty stout. Good job in your draft.
