Ted Leonsis was recently asked about changing the Washington basketball franchise's nickname back to Bullets in a radio interview on WMAL, and he responded the same way he always has. Via Dan Steinberg:
Half the people want us to change the name from the Wizards back to the Bullets, and the other half say don't you dare ever do something like that. And so these are very, very emotional issues. I do think that they get blown somewhat out of proportion. We're just focused right now on trying to make our team a high performer. We can address the name of the team another time. That's kind of a small issue for us right now."
I don't have access to the research Leonsis does, of course, but it seems like more people want to change the name than keep it.
