I'm not sure of the details but there was something recently saying knowing the ending, I think it was focused on movies, actually leads to greater enjoyment (or possibly excitement). It was surprising to me, I go a long way to avoid spoilers -- I'd imagine the same would happen with sports matches.
I don't generally watch sport, nor follow a team, but when I do it's good sport whether I know the result or not.
Some people like to know there's 'twist' ending and the thrill is figuring out who did it. I avoided spoilers for Blade Runner 2049; Harrison Ford was in it and if you've seen the first movie that's all you need know!
