Apparently by "going about it the wrong way" Favre meant Walker should have pretended to be injured and leverage an impending retirement and atrocious back-ups to get more money, instead of being honest and saying "I am worth more than you are paying me."
Of course, Walker didn't have friends like Mariucci and Peter King to cover for his every move. JFK could only dream of this kind of media protection.
Terrell Owens nails it: @terrellowens How come Favre isn't a attention whore but we get hell for having fun but he makes a spectacle about coming back its cool? Wtf ..... Child Please!
