Honestly I think a lot of the most egregious robberies are fights people don't even remember because they don't care about either of the fighters involved.
My go to example is always Michihiro Omigawa vs Darren Elkins on the JDS/Carwin card. It was on early in the prelims and both were coming off of losses. Should have been a very clear 30-27 for Omigawa.
He outboxed Elkins in all 3 rounds, butchering his face (which has since become Elkins' calling card of course). Essentially landed everything he threw whilst avoiding any returning fire with some really slick head movement. Everytime Elkins went for a takedown he shrugged him off easily with his strong judo base, it was a complete shutout.
All 3 judges scored the fight for Elkins and someone even gave Elkins a 30-27. Nobody cared. Commentary didn't really dwell on it beyond some mild surprise at the result right after, never saw any threads here about it. Never gets brought up in threads about the worst robberies, except for when I mention it.
Yet its not uncommon to see fights fhat weren't even robberies get talked about as being the worst of all time, and it always involves champions or the big names of the sport.
