For all the momentum of speculation pointing in one direction, at least someone believes Brett Favre is now capable of true retirement. [Favre's] longtime pal, Vikings kicker Ryan Longwell, would not be surprised if the future hall of fame quarterback does not return to the Vikings. "I think it's 50-50 either way," said Longwell, who is a golf buddy of Favre's and was a teammate with the Green Bay Packers. "He played so well (last season), and I think there's a desire that this team has a chance to go a long way. That would be the reason to come back. But at the same time, he was so at peace with how he played last year -- late in the season -- and that would be the reason not to come back."
