Commissioner Prize Leagues Listen Live Quarterbacks Preview Starting in 2005, Favre basically contemplated retirement after every season he played in for the next five years.
Favre's inability to decide whether or not he actually wanted to retire is eventually what led to his exit in Green Bay.
In March 2008, the Packers quarterback announced his retirement, but then decided he wanted to play again a few months later.
At that point, the Packers were already committed to Aaron Rodgers, so they shipped Favre off to the Jets.
When it comes to retirement, Favre is a Hall-of-Fame waffler who could never decide what he actually wanted to do, which means that it was only a matter of time this week before someone asked him if he would be willing to return to the NFL in the right situation.
