I saw that fight, I really like both fighters. Here is the key difference, that was at the end of rd 2, with another round to go. Merab and Ricky went the full 15 minutes, if it was stopped at 14:59, all good, but it went 15 minutes. I am fine wtih that stoppage, I remember due to asskicking by strikes by Awad, and there was still a round to go. Also, it was not from a sub that may or may not have made Merab go out, it was Rickels getting so beat up, that there was no reason to continue, fight never played all the way out, ref was cool to stop it, just like ref did not have to wait for Edson Barboza to get clean ko'd to stop that beatdown.
But Merab went 15 minutes, I think he never went out, was close to it but not out, even if people think he went out, there is nothing close to clear proof, and the fight went 15 full minutes. It's insane and not fair to go back and post fight declare such a call, win or lose blatantly unfair to Merab and a fucking gross example of misjustice in terms of the sport.
