I'm not sure you're correct on any particular point. You really don't think it's a big deal that the name is confusing? I told my girlfriend what the name of the team was minutes after the announcement and her reaction was, "Wait ... so what is the team called." I had no idea, really, what to tell her.
Well, you could tell her that the team is called NSC Minnesota Stars. It
is a soccer team run by the NSC so I am not sure you should presuppose that everyone finds it confusing. I do not. Sorry.
When you make an announcement like this, you want your new brand to be clear, simple, and relatable. I'm not sure this announcement is any of those things. They should have sent this task to an outside firm that specializes in branding.
Again I'll repeat that you might be overreacting, on the negative side. Cheer up a little. We have a team.
