How do you explain the 3 year period Jon could have moved up, talked about moving up, but didn't.
Simple answer. Money. Negotiations.
Jones entire reason for going to HW has always been big fights, big names, big paydays.
Just like getting the highest possible financial reward is the goal right now.
If you go back into the media archives, Jones is the one who first called Ngannou out for a mega fight at HW.
This was before Ngannou even beat Stipe and became the champ.
It just came down to the UFC paying him.
Problem is, this happened right in the middle of the pandemic with no crowds. The UFC wasn't paying anyone at that time.
That only changed in 2022 when they seemed to have come to an agreement behind the scenes. There wasn't any talk about money issues after that from either side.
at that point, it really just came down to ngannou being injured and in the middle of negotiations himself.
By the time both sides could align was for the march 2023 card. Ngnanou didn't sign any the rest is history.
Ultimately, it just comes down to business. No different than Ngannou leaving to box being the best business decision for him.
Everyone is out looking for more money.
