It's very convenient timing for Duggan and the city to replace the Cobo name, which few people have any deep attachment to, and sell naming rights which is the prudent move these days. They are just lucky Cobo wasn't named Joe Louis or even Coleman Young Convention Center. No sense guessing a new name as it will be whatever corporation shells out the cash.
I do agree with the thought that this renaming thing is quickly becoming a slippery slope. Here in Canada the teacher's union wants Sir John A. MacDonald, our 1st prime minister, name removed from public schools because of his treatment of aboriginals. MacDonald was the single most important founder of our country. It would be the same as removing Thomas Jefferson statues everywhere in the U.S.
