Is Brett Favre really retired as an NFL quarterback? It may seem pretty definite, but who can tell?
For years, Favre has milked the "will he or won't he" guessing game of sports writers and broadcasters by alternately leaving, returning, leaving and returning again to the gridiron.
The legendary (although sexting-tarnished) player has retired from the Green Bay Packers, played for the Jets, retired, played again for the Vikings, then said he planned to retire again only to return to the Vikings again.
Pulling retirement papers to officially collect his pension? Favre has done that twice. Injuries seem to make the latest gold watch seem final. But don't be surprised if come preseason (assuming there is an upcoming season) the rumor mill -- fueled by Favre himself -- kicks back into high gear.
