Not to bring up “randomness” again, but you still have varied outcomes and a team that won 100 on the field, but 90 on paper and vice versa. So there’s nothing too much more definitive there.
I think this transcends team sports and applies to combat and single sports as well. I think when you put together a good fight, I’m not sure one person wins 10 out of 10 times if you rewind it to the start. There’s always the chance the “better” fighter loses a couple, or more. Take the loss, work on anything that may have been exposed. Come back stronger for the next fight. Holding on to “I have a better record, lucky punch, or I beat this guy he didn’t beat”, is lame stuff coming from someone that just got beat, even if there’s some truthful reasoning to it
