Indiana University basketball coach Tom Crean isn't messing around.— Tom Crean (@TomCrean) March 30, 2014
After noticing his brother-in-law, Ravens coach John Harbaugh, was wearing a Michigan State Spartans hat - a key rival of Crean's Hoosiers in the Big 10 - he informed his 137,000 Twitter followers he would be buying a Steelers or a Patriots hat as payback.
May we recommend a Steelers hat, Coach? Indiana University gave the Steelers Antwaan Randle El, a fan favorite and key member of the Steelers' Super Bowl XL championship. His touchdown pass to fellow wide receiver Hines Ward on a gadget play sealed the victory, and will go down as one of the more exciting plays you'll see in a Super Bowl.
That, and Patriots coach Bill Belichick was spotted wearing a Florida visor when the Gators dispatched Pitt in the NCAA tournament. So wearing a Patriots hat is almost as bad as what Harbaugh did.
