They didn't do anything. They haven't accomplished anything or trained to reach a goal.
What, do you need an excuse to enjoy watching television with a bunch of people? It's just comradery and a sense of suspense, and has been around since Jousting even.
In essence, a sports game is two teams worth of fans edging and spiritually gooning to sweaty men fighting over who forcefully takes their balls. It's raw testosterone.
All they did was watch other people they've never met accomplish something they never will.
There's also admiring them for teamwork and strategy, plus people love feeling like they're a part of something, whether at a bar with a group of chums all cheering at the same time over matters of pride to someone appreciating it alone but otherwise recognizing that others are watching the same thing.
It's not too different from pre-streaming culture's interest in uniformed TV watching over Cable.

Sounds racist.
But it's about where they are instead of shit like the color of their skin. You even went on about how members of the team don't even have to be from there, like many a baseball team's players.
Sports is not a tribe. It is a company
Companies are tribes, and those who use their services are like subsidiaries to the tribe.
