If you believe in weight classes, then I don't think so. Usually 260lb+ is a fat, unathletic guy with obvious stamina and speed issues even if they have buckets of power a swift mover can evade them and just wait out the fight.
Stripe has done well in a respective weightbanding, I think that's one thing, but N'gannou represents a new one. The names on Stipe resume match a different kind of fighter; I don't think it's transferable to N'gannou.
If N'gannou was the same classification it would be disrespectful, but he really isn't: bigger, faster, more powerful than all of them with an engine and a chin.
The guy he fought was raw; both of them were, but what you can take from the fight is N'gannou can match a man his own size over a long drawn out back and forth. Someone 20lbs+ lighter simply cannot be expected to do the same (only the freak that is Cain can do that).
