Whereas once it was expected that all sports teams would be named after ferocious animals, notable historic figures or events or something else otherwise inspiring, there has been a trend in the minor leagues over the past few years to give teams somewhat silly names.
The Jacksonville Jumbo Shrimp. The Binghamton Rumble Ponies. The New Orleans Baby Cakes. The Down East Wood Ducks. Etc.
I suspect a lot of that is fueled by a desire to sell intentionally uncool merchandise to ironic hipsters. Some of it may simply be a function of branding and creating a team identity that will not, for a moment, cause the local nine to be confused with anyone else.
