Over at Mocking The Draft is a team profile for the Packers looking at the upcoming draft choices and how the offense and defense did last season. He's also concerned, just as I am, that the switch to a 3-4 might be tough:

I've never been a fan of new coaches coming in, and forcing the personnel into the new coach's scheme.  It just doesn't make much sense to me.  I understand Capers is a 3-4 guy, but why not wait a year or two, until you get the right guys in there, before making the switch?  It's not like the offense is in rebuilding mode.  Hell, they were one play away from the Super Bowl just a year ago.  Good coaches should be able to coach the players they have, not only be able to coach in their scheme.
