In reality the rankings don't matter that much outside of the elite schools Harvard, Yale, Stanford I would outside of the top 25 schools it becomes almost irrelevant and basically regional. If you want to work in Seattle your best option would obviously be University of Washington or Seattle Law School and Gonzaga could probably also land you a decent job there.
Whatever school you go to their network will be in the location of the school. The professors and career services live in the area of the school and that is where their connections are. There is a good chance people in Washington will know nothing about George Mason even thought it is a fine school. When I lived in New York nobody knew about Pepperdine, Hastings, McGeorge they just never heard of the schools because there are not many of those grads in New York although those are good schools. People at my internship in SF don't really know about Cardozo, Fordham, or Brooklyn law school because those grads don't come out to SF.
When choosing a law school outside of the top 25 I think geography should be the most important consideration since that is likely where you will end up.
