Brett Favre himself said before he ever took the field in 2010 that this season would be his last. He was emphatic.
He said that 20 seasons was something he could have never predicted, that an even number sounded about right to end on and that his last hurrah with the Minnesota Vikings was largely thanks to a feeling of obligation to his teammates.
Favre also said that he didn't think he had anything more to give to the game following his near-miracle 2007 campaign with the Green Bay Packers.
He proved himself wrong after he was traded to the New York Jets in 2008, where he started the season with 20 touchdowns (including his first-ever six-touchdown game) and helped the formerly inept Jets to an 8-3 record that had people in the Big Apple talking Super Bowl.
Then after a shoulder injury severely affected his play and led to a 1-4 slide to end the season, he further expressed his desire to retire.
That all changed again when Brad Childress and the Minnesota Vikings begged him to come join them for a run at one final title, where Favre again came back and put up a season even more miraculous and unbelievable than his final season with the Packers.
Lured back by teammates and the possibility that the magic could last one more run, Favre again returned this season, only to see it end much like his 2008 fiasco with the Jets, only much, much worse.
With such a disappointing NFL and fantasy football season, what's there to think Favre will continue history and actually come back for a 21st season? Well, history would be the key word here, but there's more to it than a trend starting roughly four seasons ago. For the five reasons, read on.
