Denver Broncos haven't had the best of luck with their stadium naming rights partners. Perhaps it's karma for all the fans who hated the idea that the new stadium would be called anything but Mile High Stadium.
First, it was Invesco Field at Mile High (the last part of the name was a lame way to appease the fans who wanted it to be called Mile High). After a somewhat rocky time with Invesco, the naming rights were transferred to the sporting goods store Sports Authority in 2011. That was hailed as a much better relationship, with a company that was a mainstay through Colorado and around the country.
