The Packers were also my "adopted" team when the Browns were on hiatus, but for a couple of different reasons: A. My wife is from Wisconsin, and though she could really care less about football my father-in-law is a "Packer Backer", so, it was a family thing. B. Because the Packers are essentially owned by the city, and we all know what distaste we all showed over the "greedy owner", and we all knew that a town owned team like the Packers was not going to be moved by some inept greedy owner.
(of course, that situation hasn't really changed. The "greedy NFL owner" is still alive and well and with us. The vacancy here in Cleveland was used by innumerable NFL owners to blackmail their cities into building new stadiums, including the likes of Mike Brown others.
Now see what happens with the city of LA prepared to build a new stadium. There will be several "greedy owners" using LA as a means of blackmailing cities for new stadium deals.
Start with Jacksonville, go to Minnesota, then to San Diego, and not least of all, Al Davis and the Raiders. And one of those will almost certainly move there.
