Kitso, stop making everything into a race issue!
I think the biggest problem is that no matter how big of a protest people come up with in favor of changing the name, the counterprotest will be bigger. People grew up with the Redskins and don't react well to change. That's the problem with changing the names to any of these teams. I don't think it has anything to do with the time between the name change and filing the complaint; I think it has to do with the fact that they know more people will get angry if they force the name change than if they don't.
I agree with you, though. I think that while team mascots like "Indians" and "Braves" are sketchy and borderline, Redskins is pretty blatantly offensive and needs to go.
