I believe ye hit that nail right in the head. A childish display (the word would be here "berrinche"; meaning one thinks by putting up a frown and acting imaturely they'll get what they want/make one feel bad for something done) which simply goes to show the lack of character on someone I thought'd be above all this shite.Spoken like a true fan. The truth is that it is business, except in Favre's case. I think he came back for two reasons.
1st and maybe the most important. He did not want to go out like he did last year. Alot of people think the way he faded at the end of the season damaged his legacy. I think they way he can't walk away will do more to tarnish it than the way he finished last season.
2nd and maybe the funniest. He feels slighted by the Packers for pushing him aside...
