Everyone's previous predictions on the Big East's demise have been so accurate. The Big East has high profile program in big cities that make up the majority of the nationwide basketball fanbase. The SEC draws 6,000 fans to midweek games, and half of those are student tickets that are either free or virtually free. No one cares about basketball in the South outside of Kentucky, North Carolina and maybe Tennessee.
Remember when everyone said that football drives the bus? Football will be a regional sport in 10-15 years, and most high schools in the northeast won't even play it. Any sport that turns a large percentage of its players into crippled vegetables or sociopaths has a limited shelf life once people understand the causality.
