DEFENSE

I am looking at a some defenses that can help me
I currently have SD's D they have week 5 bye

who would you like out of this bunch available

GB - they have week 5 as well but I think they may be the best of the bunch
Seattle - I like there division and I think they are improved from last year
AZ - I like their fantasy playoff matchups, Det, Stl, and I think SF
Atlanta - are they better?
please chime in if you got an opinion

I'm looking at Sea, Atl, Hou, Indy, Denver and Oak myself b/c I have the Jets D and they face NE this weekend
