Coaches, players, and team owners consent to match fixing that’s for sure, because match fixing wouldn’t happen in the first place if there are no insiders involved in the bets. Most of the time, they do these on leagues that don’t really matter, but still is a hype one yet the profit that they get from winning the games aren’t really something compared to the potential profits that they can get on match fixing. I certainly would bet on such matches in a heartbeat if I do have the insider information, though a part of me thinks that it is wrong and unethical, but whatever.
^ For sure they also get paid for this kind of fraud.
I heard on boxing before that there is a match-fixing and also in NBA there is a match-fixing in order to continue the series longer.
I don't know how they manipulate such games but I think for now it is rare that there is match-fixing, players have their dignity and fighting with their own reputation and I don't think this is very common to happen. I could probably be unethical because there is no proof about this, because it could be a serious case if ever someone caught.
