I'm curious why everyone seems to have collectively agreed that UM will go to the Big 10 and that the SEC is not an option. I'm not so sure about that.
There are no real "insiders" when it comes to conference realignment. This isn't recruiting where you're dealing with dozens of coaches, family members, representatives etc, any of whom could spill the beans.
When it comes to moving conferences, the circle of people who really know what's going on between a school and a conference is shockingly small. People may hear certain things through the grapevine, but that doesn't mean **** really. So I would take anything you read on twitter or whatnot with a large grain of salt.
