Of the eight NFL teams that won divisional titles in 2012, six of them also won that division title in 2011. The two teams that went to the top of their division in 2012 (but not in 2011) were the Atlanta Falcons and Washington Redskins.
The Falcons last won the NFC South in 2010. For the Redskins, this past season’s divisional title was a long time coming. The Redskins last won a division in 1999; that drought was tied for the fourth longest in the league.
