GW could be a #2 seed...so I don't think they qualify as a cinderella. Neither do BC, MSU, or Tennessee. Teams that are ranked that high shouldn't be called cinderellas...but I agree, they'll make noise.
I think this thread will be more appropriate after Selection Sunday, when we actually know who's in. There are a bunch of times I might strongly consider to be a cinderella, but they might not even MAKE the tourney.
