Check out the MN United website, and I think most would agree that the logo, uniforms, brand are good. (For the record, the nickname is the Loons - and the jersey and logo depict a loon - the work of Zeus Jones). Even though the Kicks had a season with avg attendance above 30k (second only to the Cosmos), most MN soccer fans identify more with the Thunder/Stars and now the Loons. And with ownership investing in the team and the brand, I think the Loons will only get better.
No reason to bring back the Kicks.
