If the Big East and Conf. USA collaborate on membership or a playoff game (e.g. if BE is at risk to lose BCS status, they might salvage it this way), then the Mid-Majors/non-BCS schools might look for a play-in approach by either pairing up BE/Conf USA or MVC/WAC or qualifying by playing each other's champion.
MAC and Sunbelt may or may not be party to this. Comments? Either way, WAC-East or Conf. USA-West needs to occur for us.
Lastly, what is Army hoping to do?
