It's not the same though Bro. The Titans took the color/name etc. The Browns still had everything that made them, "The Browns" I think that should Seattle get a similar deal to Cleveland, the naming rights, colors, and a promise that they can have a team within the next x years it'll feel the same to the fans.
I'm not from the area, but I'd nearly forgotten that the Browns moved to Baltimore, I think an expansion Sonics or a relocated team to Seattle five years down the line would lead to the same thing in most fans eyes.
