This is a pretty tight one for me -- You split the value pretty well among the groups.

But I'll take Ryans and Rivers and LFB: 

Fletcher-Baker is getting up there in age (33), but he's been a top 5 LB for the last 3 years and should have a few more years of productivity; Ryans has also been a top-5 stud his first two years in the league, and at 23 still has a long great career ahead of him; and Rivers gives you the consensus best of the rookie LBs to also build on for the future.

I like Barnett, Harris and Connors.

Barnett is still the heart of the Packers defense and will easily hit 100+ tackles...Harris is in a situation where he could easily be the best linebacker coming into 2008...Connors has potential and should get some playing time...possible 40+ tackles...should play special teams and excel in tackles...

I do like the Beason list, but not sold on Lewis being his same self or Mayo making great contributions.
