Can someone please explain to me why the Purdue-IU rivalry is not on this list? I understand that Purdue is not as "glamorous" than a Duke or Syracuse and that it has not been much of a rivalry the last few years with IU rebuilding but I don't see how you would not include the Purdue-IU on this list.
