Except we have actually seen Ngannou's improvements. Not hypothetical gym improvements.
Some 2022 account with yellows isn't going to pull the casual card on me lol.
Sad you place so much value on internet points, but nonetheless you are right. Sergei would not have a chance trying to wrestle Ngannou. He tried to wrestle Overeem and failed miserably, he does not have offensive wrestling skills and even if was full time at AKA the last 4 years he still wouldn't develop offensive wrestling skills to counter Ngannou's wrestling defense. To be a great offensive wrestler you have to have been doing it your whole life, but elite athletes can develop decent wrestling defense fairly quickly these days.
Sergei has brought a little bit of life into a pretty dead HW division but whether it is against Ngannou or Gane, he will have to tighten up his striking to compete against more technically sound opponents.
