A lot of where Ngannou goes from here will depend not only on his recovery ability but, even more fundamentally, old fashioned work ethic. Sokoudjou was rather widely known as being the kind fo guy who let whatever physical abilities he was born with carry him for his whole fight path. If Ngannou does that he could falter and fall even harder. Certainly how much he gains the ability to fight effectively for 5 rounds is gonna have a lot to do with that.
I do have to say, this time I made sure to take note of the issues involved in overpromoting a fighter, especially at this weighty class, based solely on power and intimidation power. This time I called it well before it happened.
