All in tends to mean sacrificing the future for (hopefully) results now. TT will never be that guy. The change is more of realizing there are more holes than can be filled in the draft / UDFA, and being better prepared for inevitable injuries (e.g. getting two TE's that are better than R.Rodgers.) Replacing Lang and Shields still needs to be done.
The Packers have enough talent to win, as long as there are no glaring holes to be exploited.
