You can't understand how a crowd might be able to influence a judge if he scored a round against their fighter, when he is scoring subsequent rounds? Or that after a close round he might be inclined to score that round in favour of their fighter to avoid a negative and intimidating reaction? Not sure you have a great grasp of human nature, tbh...
Robberies by far. Sure some of those other options make a mockery of the sport too, but if a governing body can't even have officials follow their own rules to award results then it makes the sport a total joke. Imagine an NBA team scoring more points than the other one but the governing body awarding the win to the other team anyway, it'd make the sport utterly pointless.
Fielding is absolutely irrelevant at SMW. He is domestic level at best. You are talking as if he is facing Calum Smith or George Groves!
