In the Shevchenko/Cachoeira fight. Mario has become a meme at this point and I haven't seen him ref since. "Imagine if Mario was reffing that fight," is what I often hear but can you off the top of your head remember another fight where Mario had an incredibly late stoppage? I'm sure he's had some bad calls, but in that regard, he's not the worst. Far from it in fact. Cachoeira was outmatched but she was never even close to being KOed unconscious. She wasn't taking any damage that is above the norm for MMA and only in hindsight do we know that she wasn't going to make a come back. We've seen far worse. Look at a fight like Gaethje/Poirier, JDS/Cain, Lauzon/Miller, Mir/Carwin, Weidman/Munoz and countless others for fights where you should be worried about the health and career of fighter. Even Pennington/Nunes was more brutal.
