Jim, John Harbaugh don Indiana crimson in show of family support

Indiana had a pair of famous football brothers in its cheering section for Friday night's Sweet 16 game against North Carolina.

Baltimore Ravens head coach John Harbaugh and Michigan coach Jim Harbaugh wore Hoosiers T-shirts and sat behind the bench during the game in Philadelphia.

This is a family affair for the Harbaughs. Their younger sister, Joani, is married to Indiana basketball coach Tom Crean. So even though it's a bit odd to see Jim Harbaugh wearing the logo of a rival Big Ten school, he has often come out to support his brother-in-law. And Michigan-Indiana isn't exactly a stirring football rivalry.
