The Baltimore Ravens and San Francisco 49ers already met this year on Week 12.
The Ravens came out on top that night, but a rematch of that showdown would make for a fantastic Super Bowl.
Jim Harbaugh took over the San Francisco 49ers and led them to a 13-3 record. The 49ers were one of the biggest turnarounds in the NFL this year after they limped to a 6-10 record in 2010. Harbaugh improved the defense and simplified the offense for Alex Smith.
John Harbaugh has had the Ravens in the playoffs every year since he took over in 2008. The worst record they've had was 9-7 in 2009. This is his first year winning the AFC North and led his Ravens to the No. 2 seed in the AFC.
Both teams have a lot in common and would make for a hard-fought battle in this year's Super Bowl.
