In recent years I've felt this way too. He was damaged goods when Foreman got him. Frazier wasn't the same after FOTC. Frazier of 69-71 stops 73 Foreman inside 8-10, but not without some turmoil due to Foreman's strength & punching power.
I think tyson fury is being overrated in this forum because of his win against deontay wilder. Wilder ducked joshua and hadn't beaten a top 10 heavyweight yet and almost lost to luis ortiz. A win against him doesn't hold that much weight to be honest
I also think George Foreman beats FOTC fraizer I'd just be a closer, much longer fight. I always though it was foremans style and power that made him beat fraizer so easily
