Since 2002, when the divisions have been re-aligned, teams that have played the AFC West had not won the SB. The last one was the Raiders that lost in the 2002 SB. That pattern was broken this year when the Ravens played the AFC West but won it all. Pats came close last year with the same set of divisions but fell short.
The new pattern that seems to be alive and kicking is this. A team that plays the NFC East has won the SB since 2006.
2006 - Colts
2007 - Giants vs Pats (both played NFC East)
2008 - Steelers vs Cardinals (both played NFC East)
2009 - Saints
2010 - Packers
2011 - Giants vs Pats (both played NFC East)
2012 - Ravens
Next year, the AFC West and NFC North play the NFC East. Candidates to win it all would be Packers, Bears, Broncos, Chargers
Packers win it all next year!!!
