It’s been more than nine months since the Denver Broncos were officially granted naming rights to Mile High Stadium following the bankruptcy of Sports Authority, the company that previously held them. Thus far, no business has stepped in to fill the void, and while a marketing expert believes a rights agreement will likely be reached prior to the start of the 2017-2018 regular season, he thinks smaller, less stable firms should stay away lest they suffer the same fate as Sports Authority, whose doom, he says, was hastened by the deal.
