The Falcons "being the only team interested" is false; another slight to make BB look bad, I guess. Both the Eagles and the Cowboys reached out to him, but he turned them down. They obviously can't have him in for a public interview because they already have an HC, and they don't want to fire their HC unless they are reasonably sure that they can land BB.
Additionally, we don't know what other teams may have contacted him, that DO have vacancies, that he denied. It is supposition that BB requires certain things in the front office. None of us know what his requirements are.
