At a real high level, if the Packers do not acquire known commodities at S and ILB thru trade or FA, I sure as heck hope they have an extremely high degree of confidence that the draft/player development route (such as Hyde) accommodates those positions.
I think you are saying "I hope, since they didn't sign someone else's guys, that they hope their own guys and rookies will be good enough."
My answer... I think so.
In words for you... I think it is reasonably affirmative, at a high level, that this team, as designed, most likely meets the needs to some extent what the coaches desire, save for unforeseen circumstances (such as death) and within the parameters of draft and develop.
