I dislike the NFL as a product on the field generally speaking, but it is the sport that probably operates the most like how the real world does. There's some corporations that just operate on a higher level, and got a floor that rarely if ever dips. Some other smaller dogs just get an occasional chance for their ceiling to meet them dudes floor.
Chiefs pretty much been Nike, Baltimore been more like Adidas. You doing alright, but you get a Yeezy or Beyonce/Ivy Park every once in a while. Then Nike comes out with another classic retro around December and just dominates again.
