|How's your Luck?|
|This is the first time in 21 years - and only second time ever - that three of the final four teams are quarterbacked by a Super Bowl champion. New England's Tom Brady won in 2002, 2004 and 2005, while Green Bay's Aaron Rodgers (2011) and Seattle's Russell Wilson (2013) have one win apiece. Andrew Luck, of Indianapolis, is the odd man out.|

Defending Super Bowl champions Seattle beat the Carolina Panthers 31-17, putting them one win away from a return trip to the NFL's championship game as they bid to become the first champions to retain their title in a decade.
