I don't know, the fact that you have to name so many reasons sure seems fishy.
Your first point is kinda strange as Fedor vs Overeem would've sold itself, there was no need to "build" any fight with Fedor back in the day. Those were Scott Coker's words. Not debatable.
Also, Fedor lost to both Werdum and Bigfoot. Irrelevant here.
So Overeem was unranked and a Champion at the same time... ok, I'll indulge you. But Fedor had no problems fighting the likes of Ogawa or Fujita either instead of higher ranked opposition. So there's that. Pride worked differently. Fedor fought Ogawa in a tornament. When Fedor signed with SF he was fighting nothing but top fighters. Overeem would have been his first non top ranked opponent since 2007.
Yes, Overeems title reign was a joke, I agree. And because of that Fedor should've pushed for that fight. His fights during that period weren't really against the creme de la creme either. #4 Sylvia, #2 Arlovski, #2 Barnett (cancelled), #6 Rogers. As I told you, Fedor was only fighting top fighters.
So Fedor prefered to fight another ranked opponent but not the title-holder because he doesn't care for the belt? Top wins are better than irrelevant belts.
Overeem ducked Fedor? To me it seems the other way around. He did. He was offered the fight but ran to K-1.
So you'd say guys like Mark Hunt and Werdum didn't evolve over time? Sorry, but that's just dumb.
