Brett Favre has officially filed his retirement papers with the NFL, a move many people anticipated, especially after such a horrid 2010. Will Favre hold true with his fliing and never play an NFL game again? It is possible for retired players to come back, but with his consecutive starting streak gone, the Vikings in a battle with the city of Minnesota regarding a new stadium or the possibility of moving, and being in his 40s, Favre will likely retire this time. He was one of the best quarterbacks to ever play the game with multiple MVP awards, a Super Bowl, and owning the main passing all-time records.
