There was the Music City Miracle. More recently, the rise of Patrick Mahomes and the Chiefs has proved an effective counterweight Ed Davis Jersey to Buffalo's resurgence in the 2020s. And you can't forget Tyler Ba s' spurned chip shot during last season's AFC Divisional.All of that is to say, it's been tough viewing games specifically playoff games if you are covered in the blue-and-red.MORE:Yet head coach Sean McDermott believes good times are ahead.
