Nah. Yan vs O'Malley wasn't a robbery. I scored it for Yan but it was a pickem.
Round 1 is a toss up, I scored it for Yan but I can see the argument for O'Malley taking it.
Round 2 is a dominant round for Yan.
Round 3 O'Malley outstruck Yan 40-15 in significant strikes and busted his face open. Yan landed a couple of good counters but most of his offense consisted of shooting for takedowns he did absolutely nothing with.
This is what I mean, a lot of your examples are not robberies. They are close fights that generate a lot of outrage because the guy most people wanted to win didn't get the decision.
I do think Yan won but it was not the blatant blowout robbery that people are crying about.
People don't like O'Malley which is why this fight is getting the reaction it is. It's similar to Hammill/Bisping which you also listed and also was not a robbery. That too had a fighter that nobody liked getting the nod in a close fight.
I think you're generally right about robberies/ split decisions, but not in this instance.
Tolerating other opinions is important for the sake of objectiveness, so claiming one's own has to be right is never a great idea.
So let's just assume that opinions vary since the fight was competitive. Funnily enough, they don't.
Out of 26 media representative not a single one had O'Malley winning the fight. 7 had Yan winning all three rounds.
Just by chance there would've been at least a couple scores for O'Malley. But there weren't.
Let's just say a fight is exactly even, but draws aren't a thing. The most likely distribution of scorecards would be 50/50. Now if you take only 3 scorecards a 3/0 distribution is not that unlikely. Take 26 scorecards and your chances for a 26/0 distribution will be 1 over 2^26. That's essentially zero.
The fight was close, but still not close enough for anyone to score for O'Malley winning. Which would've happened just by chance if the fight was actually close enough.
If the disagreement with the judges is only 50/50 then nvm. Even 70/30 might not be a clear robbery. But when the 80/20 mark is passed, the chances for that happening are just too low to be random. 100/0 distribution as I said, is just not happening by chance.
