Seriously, how hard is it to see the different factors surrounding Indiana basketball compared with Iowa. They have history, basketball is synonymous with the state of Indiana thus at IU basketball is number one, they have nothing else, their football team sucks and always has, they have a championship history and are recognized as one of the greatest programs ever, Crean came in with hype, coming from a team that he went to the final four with.
Going to an Indiana game is like going to Lambeau Field, Yankee Stadium or to a hockey game in Canada. If you get a chance to do it, you do it as a sports fans. Iowa doesn't have that.
I could go on too.
