When the Dolphins fired coach Brian Flores, he poured a can of gasoline on the floor and lit a match on the way out. The head coach revealed some startling truths about their season. Allegedly, the front office instructed him to tank and lose several games but Flores refused to do this (via CNN).
Furthermore, he claimed that the team offered him money to stay quiet after he lost his job. He also said that three franchises showed racially dubious practices in their hiring processes as they lied to him. Miami received a massive NFL punishment for their lack of a moral compass.
