For the first time in Super Bowl history, the coaches of the two teams were related. Baltimore coach John Harbaugh is the older brother of San Francisco coach Jim Harbaugh. As a result, the game was nicknamed the Harbaugh Bowl. The Harbaughs were also the first brothers to coach against each other in NFL history when the two teams met on Thanksgiving Day in 2011 in Baltimore. The Ravens won that game 16-6.
