Some of you are making WAY too much out of this. J/B Russell said that he wanted to go to a city that wants to win doesn't necessarily mean that he thinks that Seattle didn't. It's quite possible, perhaps probable, that part of his criteria for being traded included going to a team, like the Broncos, that have a rabid fan base that "wants to win". There are other teams, like the Chargers, Cards, Jags, Jets, Giants, Rams, etc, that don't have nearly as passionate of a fan base as do the Broncos, who rank up there with places like Seattle, Green Bay, Dallas, etc, that have highly supportive fan bases.
Besides, he's gone now, no longer a Seahawk. Who gives a rip what he says to his new fans?
