NFL is a microcosm of american politics. Two opponent teams, each has a trainer, a rich donor, some ideology and millions of fanatics who vote for their team no matter what. It may seem like the goal is to win the game on the stadium, but behind the scenes it's a well calculated auction of advertisements.
I disagree. The point is kinda spot on. Their end goal is to have their team perform the best possible in order to sell out tickets/stadiums/merch and have high ratings from viewership and syndication.
