Syracuse, for instance. They used to be the Orangemen. Now they are the Orange. This is even dumber than if they had become the Oranges, and that would have involved a large citrus fruit mascot. The "Orange" is meaningless. I mean, did Holland complain?
Or, say, Dartmouth. I'm not saying they had to remain the Indians (which apparently they only ever were unofficially--see link in comment--"official" mascots are a pretty new thing), but I think they could have come up with something better than the "Big Green." Because that makes you look like you want to be Cornell (who are the Big Red), or at least that you have less imagination than they do. What about the Beerkegs?
On the score of stupid team names of the idiotic quasi-collective noun variety, we also have the Harvard Crimson. But at least they've been the Crimson for a long time. This is not as dumb as the Utah Jazz, which makes no sense at all. What about the Utah Mormon Tabernacle Choir, or something? (A comment notes that they used to be in New Orleans, so it makes sense. I knew this. You'll note that the Titans realized that "Tennessee Oilers" was stupid. And "Jazz" is a lousy name for a sports team anyway, whether or not it's relevant.)
Name your team something intelligible, meaningful, and plural, please. None of this post-modern placatory nonsense.
