@AstralPanda most fighters also seem to agree that Jon is ducking Tom, for whatever that is worth.
As I said in my initial post though, there's a lot of factors at play, not just whether a fighter is tough or deserving.
As fans, it's easy to look at things in the context of the best fighting the best in terms of skill. However, this is a business and everything needs to be considered.
When fighters reach these older ages, universally and ubiquitously, we see them start searching for the money fights, the big names with the goal of creating a big event. It's not something unique to Jon Jones.
As DJ said, he's retired and only coming back for a fight that gets his dick hard.
So, it's not just money but also motivation, during a time when fighters are getting older and struggling to find the fire they once had in their youth.
These are all things that are going on in the mind of a fighter during those later twilight years, when you only have a short time left.
Tom doesn't have some mythical, legendary skillset that Jones hasn't already seen in his career, so from his perspective, what is gained from taking the fight?
It pays less, it's a harder fight, offers no legacy points, no accolades, and might even be a harder fight to get motivated for, since all of those elements aren't there.
It's easy to just say a fighter is ducking, but it's not that simple. These niche and nuanced elements also need to be considered.
