A GM is only as good as the talent scouts that he surrounds himself/herself with. Thompson had a great staff that got picked to pieces as time went on. The same happened to elder Wolf. Gute seems to have a good staff around him. The way I understood it, Gute and Elliott Wolf were friends. One got the job and decided to move on, which was a good choice for a 30-something kid. Dorsey was potentially putting together a good foundation in Cleveland.
I really don't see why Wolf would want to come back, making at best a lateral move but more likely a step down to re-join the team. That said, for anyone that has paid attention to the Packers front office, Gute could make up any position for Wolf or Highsmith if he wanted them back. Alonzo was probably more highly regarded in the field based on performance than Wolf. I would be ecstatic if he came back.
