They tried replays 50 years ago and the umpires refused to budge and so they banned them so fans couldn't know.

the above is from https://en.m.wikipedia.org/wiki/Ron_Luciano 's book but wikipedia doesn't mention it. Though it was 40 years since I read the book so maybe I don't remember right?

I think it makes the game human. also football with replays on ever play is too slow.
