Now here's one that really needs to be accomplished. What would we call a 12 team Big Ten. The conference is going to regret the day when the name change takes place, given all the tradition of the name "Big Ten". Still it's got to happen and the new name has to be a fantastic one.
I vote for (and even included it in my screen name): Big Dozen (realizing there might be some confusion with the Big XXII, but what the heck: it was the Big Ten who came up with this Big "Number" naming system. So Big Dozen is my favorite.
Great Lakes Conference
North Coast Conference
If we're taking what WOULD happen into account, you can throw out any name that specifies a region of the U.S. With the marketing-oriented world we now live in, they would never "limit the sales potential" that way.
I guartee you they will use the phrase "we are a national conference" at any announcement session.
American 12 or Big American seem very likely to me.
