He sure did. However, he had no choice. He was 10+ years past his prime and at his age it was physically impossible to be the same boxer he was in his prime. Exceptions are not the rule.George Foreman did it
This, is Holloway the one still doing it.Gaethje doesn't take all that much damage anymore.
He was badly badly rocked quite a few times in his first few UFC fights, but he has gotten significantly smarter about angles and distance. He still plays a dangerous game, but blocks with his face quite a bit less.
