1. No... he didn't have the patience to wait for Wolf to hang them up here.. he knew he was close but "needed" to have the entire say "now". It blew up in his face in a way.. yes he got them to the Superbowl... but inconsistent along the way. He had a Hall of Fame caliber start to his head coaching career here in Green Bay, had a chance to become a legend.. he spit the bit.
2. Favre gave the Packer that legitimate player that they could build around and recruit players (A little different back then.. see Reggie coming to Green Bay, but kind of like the Pats have now)... once #92 came aboard.. they had little trouble selling the franchise to short term quality role players and top notch FA as well.
Talent doesn't always mean success though.. so it was a successful marriage between Wolf, Holmgren, a hell of a lot of talent at the assistant level and some damn fine professional players. One hand shook another.
I look at the assistant coaching staff as a very large key that wasn't proposed in the original question.
