I don't think they're trying to lay claim to the number "12" itself, because that is retarded, but just the idea of the 12th man.

Another thing I forgot to add is that a bunch of former A&M coaches have now ended up in Seattle, just about the same time the Seattle 12th man starts to get big again.
