Ravens-49ers: Which brother wins?
To make it extra special, San Francisco's offense will need to outdo Baltimore's. The Ravens have scored 90 points in three games, and the Niners have 73 in two.
Baltimore's defense has made big plays against Andrew Luck, Peyton Manning and Tom Brady. Now it gets an entirely different type of quarterback, Colin Kaepernick. His combination of running skill, powerful arm and surprising cool for a second-year pro makes him particularly dangerous against the Ravens. Baltimore does not have the fastest defense in the league.
Then again, the 49ers must deal with Joe Flacco, the only QB to win a postseason game in each of his first five seasons. Flacco also has six road playoff victories, a league record.
He's also outplayed Brady, the most successful quarterback of the last dozen seasons, in two straight AFC title games.
But he has his critics because this is his first Super Bowl trip in five tries.
"I think there is definitely a part of all of us that hear things and when somebody doubts what you want to do, you definitely go show them that they may be wrong," he said. "I think for the most part we play for each other and that stuff is kind of a secondary issue."
While the Ravens and 49ers play for each other, the Harbaugh brothers, John of the Ravens and Jim of the 49ers, will go against each other in the first Super Bowl featuring sibling head coaches. They've had fun with the topic this week, but it will be as serious as football can get on Sunday.
With older brother John coming out on top.
