The fan. The single most important element of any sport.
The athlete, the coach, the game—all of those things are just there for our entertainment.
What really matters is the fan. The rest literally get together at our bidding to perform for us. We pay the money to watch them do it. We buy the products that the advertisers sell that gives the money to the networks that they give to the league that the league gives to the teams that the teams give to the athletes, the coaches, and even the cheerleaders.
Yes, it all starts with us.
Yet while the fan has all the power, there are those of us who misuse our power and neglect our responsibilities, the biggest of which is a simple task: to merely not be annoying.
It's not complicated. Just avoid being these guys, and you'll avoid being one of the most annoying fans in the country.
