People derive enjoyment from fandom in different ways.
Some derive pleasure from watching their team playing and rooting for them to win.
Some derive pleasure from learning more about the game, scouting players, thinking about the draft, studying analytics, and so on.
Then there are those who derive pleasure from wallowing in preemptive misery at the thought of their team losing, and see every win only as an opportunity to anticipate greater future disappointment.
Still others derive pleasure from explaining how there's only one true way--their way--to be a fan, and if, say, you enjoy a regular season victory, you are a lesser being than they are.
To each his own.
